Group 1 Metals - Reaction with Water

[Statiickz]

I want francium!!! >:( jks i know the danger :)

[AuroraShadowLuna]

Thanx for this vid, has helped my gcse chem! (because I paid attention in class

[ADEOmovies1969]

Francium is no were near the most rare element on earth an there is way more than 30 fuckin grams cos some one showed 100kg of francium explode duh.

[GossyHD]

francium please!? jks

[y0utubedude96]

Uhhhh you missed Francium? JKJK I know you would explode :)

[JasonJia11]

@y0utubedude96 yeah, it's highly reactive, and it's radioactive, :P

[lilmisrandom123]

thanks! you guys saved me from a detention :)

[happyy4ever]

i have a question i need to answer for school on this vid-anyone help?? it is- how are these all similar? ty x

[JUDE3761]

@happyy4ever they are similar because they all produce hydrogen gas

[happyy4ever]

@JUDE3761 thankyouu very much x

[spartanxdj]

@unholysanta even puting that amount of francium in water is like detonating a block of c4, abd if its the rarest element how would he get it?

[unholysanta]

two problems

P1 how the hell did you get your hands on caesium

P2 in the desription why is francium not there, it may be rarest element on earth but its the most reactive

[LoveEverythingx3]

cool but ruining the air with smoke

[gamerpolis]

Fracium has only 30g in the world thats why they cant make one

[jaypay777]

why do no videos have real francium reactions?

[TheKoolKid6661]

@simcardsokl it's incredibly unstable , it could react with the air and it'd be a huge explosion

[PhantomSkillz57]

@simcardsokl It's because it's so unstable and dangerous francium contains 33 isotopes all of which are unstable, plus unlike the other alkali metals in family one on the periodic table of elements francium is also a radioactive isotope. Pure francium would have to be stored in a airless radioactive resistance container otherwise it would explode when exposed to the air (air contains water vapor) and it could cause damage to cells including human cells.

There is your answer my friend

:D :D :D

[clf0226]

suddenly feel that it's so good to have a website called youtube,it let us sharing our experience and study more^^

[MrInanimated]

Nobody seems to remember that francium is the most radioactive natural (well, an element before uranium anyway) element with a half life of 22 minutes. If you tried to gather together a feasible lump of it the sheer amounts of energy given off by it would make the francium evaporate instantly. And that's why you don't find francium in chemistry tests.

[achmedfu]

i've watched 14 seconds of it and already im hoping that he doesnt through the same amount of caesium in there ohe'd better get the f*** outta that room! lol

[Hardstyle3701]

@kayra97: Francium is a ridiculously rare element... estimated that not even a kilogram of it can be found in the Earth's crust. On another note, you would need a HUGE amount of francium to make an explosion the size of a nuclear bomb. Just because it is the most reactive element known does not necessarily mean it is THAT reactive. :) I am not sure about this but some compounds may actually be more reactive than Francium.. although this is just a guess.

[guywholikespie1]

@Hardstyle3701 fluorine is the most reactive element in the periodic table

[kayra97]

y didnt u do francium it reacts with oxygine so jus chuck it in the air the explosion is the same amount of a nuclear bomb.

[hdhdhdhgfhfghgjcfgj]

Francium + water --> Franciumhydroxide + hydrogen + extermination of all living things within a large distance

[mompnomp]

just coz francium is a tad dangerous it doesnt mean u cant show it to us on youtube

[1966065015]

@mompnomp

you cant. lol...

nobody can collect francium without it instantly reacting and changing into a compound of soemthing else.

and it would be very dangerous

[teperc9702]

awwwwwwwww cmon why not francium?

excluding the fact that it might badly hurt you...

[Tyrmidace]

Putting francium, if you could get it, in water would be quite pointless. It releases about 600 times as much energy every second through radioactive decay as the total energy that would be released from the chemical reaction with water. You wouldn't notice the difference. In fact, you probably wouldn't notice anything, as being in close proximity to something which releases energy equivalent to dropping a few kilos of sodium in water every second would likely leave you somewhat deceased.

[essap1999]

tytytytyt

[giratina3761]

u havea very good scientific way of putting it in water by dropping and running

[qwerty83483]

francium

KAAAAAABOOOOOOM

[ealvarou111]

well you could use potassium in christmas :D

[codplaya50]

no francium:(

[panztrix840]

@codplaya50 Francium is extremely sparse, radioactive and incredibly explosive in water

[azurankun]

maybe Francium is too reactive that can burn the house

[thatpieceofgrass]

It's called cesium fucktards learn to spell

[thunderfirebolt]

@thatpieceofgrass actually... Caesium is the spelling recommended by the International Union of Pure and Applied Chemistry (IUPAC). The word "Cesium" is used mainly only in the US.

[IntenseJonasFan]

@thatpieceofgrass YOU fucktard, it depends on whether you're AMERICAN OR ENGLISH.

The English spelling is Caesium, whilst the American one is Cesium...

[ZGrind94]

why does no one show francium?!

[GuruGirishMaster]

@ZGrind94

It is so explosive that hydrogen liberated will immediately burn fiercely with an intense flame. However the main reason for not using francium is because it is radioactive and will significantly damage living cells with neutron bombardment.

[ed5414]

@GuruGirishMaster that and it lasts only 22 mins.

[AshZombine]

@ZGrind94 Francium is radioactive.

[Jony95153371]

nyc .....

[arsicola11]

they r highly reactive when going down the table

[mttlsp]

Awesome video :-)...but Lithium was misleading. Try using a gram in 50 mL of water...it'll blow up like fireworks.

[GuruGirishMaster]

@mttlsp

No, it was true. In fact, the least reactive group 1 metal is lithium. And most reactive is francium. The reactivity increases down the group since the atoms increase in atomic radii as we descend and become more prone to loose the outermost electron so as to acquire the configuration of a noble gas.

Hoped I helped.

[essap1999]

this is called priodicity

[team7uppz]

wheres the francium or your scared of blowing up your fingers

[e55exeagle]

Our chemistry teacher always stopped at potassium (can't think why...). Nice to see it done with rubidium and caesium too :)

[TenteixSaigo]

@e55exeagle b/c the reactions will get more violent as you go down the chart. he used very little rubidium and cesium, b/c that cesium reaction was obviously rather mild comparetivly.

[alexzhang101]

science is very fun and interesting!!!! it is at least 1000000% better than sitting on a chair and do nothing!!!

[alexzhang101]

yeah, francium cannot be used because

1. It is highly radioactive

2. It is very rare, no natural isotopes exists in the nature, so it is also extremely expensive

3. It has a short half life

4. It is too volatile, even exposing in air for a second can form an oxide layer

[dragefyr]

@alexzhang101 Oxide layer?

[alexzhang101]

@dragefyr no, when francium reacts with water it produces Francium hydroxide (an alkaline) and hydrogen gas, not an oxide layer, that is when metals reacting with oxygen.

[gunsnflamethrowers]

@eofregene no-one can do francium coz its extremly radioactive and cannot be bought legally and is extremely rare

[mrvrichguy101]

Ha my teacher put potassium in and just stayed he put a cover over it though

[darkdjo]

That's a great video. I'd like to see what it happened with Francium but it is so instable...

[eofregene]

no one ever does francium

[WheresxYourxGod]

a piece of francium that size would be interchangeable with the explosion of a grenade or higher its serious stuff. I interned for a chamistry lab and the professor showed us an example in a secured container.

[neil9327]

@eofregene That is because it is extremely rare in the earth's crust. Only around 10000 atoms of it there.

[FaizBaloch1]

can you plz add the exact amount of metal was used in these reaction..plz put those amounts in grams....thanks

[TheSockFilms]

What about francium?

[kriegkatse]

Francium is highly radioactive and occurs in nature only as a short lived species in the decay series of heavier elements like uranium. you would never be able to purify enough fancium to be able to see this reaction

[DillonRHall]

imagine the reaction though! it would be amazing

[instructabletoco]

@kriegkatse Then why isnt it in the actinides group of the periodic table of the elements?

[kriegkatse]

radioactivity has nothing to do with its location on the periodic table, the groups of the table are based off electron configuration, the reason most of the actinides are radioactive is because of there mass and proton to neutron ratio, light elements can be radioactive also, such as hydrogen 3, also refered to as tritium

[instructabletoco]

I knew about the electron confuguration i just assumed that the radioactive elements were all in the actinides. That was simply what the textbook said. It is a fairly old textbook. The periodic table is constantly changing so some of the newer textbooks are even wrong.

[kriegkatse]

its an understandable assumption to make without thinking to much about it. I am a physical chemist so i deal with these concepts fairly often. But just as some extra trivia, carbon 14 is radioactive so thats how they do carbon dating, by measuring what percentage has decayed, and the instability in heavier elements becomes noticable past lead, just about all isotopes of all the elements past lead are measurably radioactive except ones like uranium 238, which are just barely radioactive

[MrDuckcheese1]

only created for about 4 secomds when you do nuclear experements + its radioactive

[YuGiOh2Pokemon]

francium is an earth alkai metal and is impossible to buy. it isnt sold at all because a peice of fransium the size of a baseball could probably blow up all of north america

[crapkillerz]

god you are so misinformed... You cant buy it because it is radioactive... its longest lasting isotope lasts for about 22 minutes before it decays into another element... ALSO, francium is an alkali metal, NOT an earth alkali. Get your facts straight, bub.

[zalvoz]

its alkali metals :)

[KDMVs]

This the alkai metals and this video how they react with Water =D

[Hellman098]

Francium is radioactive and has a half life of less than a minute

[tugfngjfuvj]

and theres way too less of it to get ones hand on it :-/

[Hellman098]

No, it is becuase they have more 'electron shells' which means the force keeping the single outer electron in place gets smaller and smaller as you go down the table, so the electron is lost more easily as you go down the table.

[gangsterfromdaghetto]

@Hellman098

Due to shielding?

[croutonicus]

Francium is not that rare it can be isolated in an enviroment were it decays at a slower rate. The problem is it reacts so violently with air it doesn't occur in its pure form naturally.

[GunnerAL14]

no, franicum is extremely rare as it is decays very quickly b4 u can get it

[artemisf125]

is there any video anywhere with francium?

[marcarrietharden]

lol.... homework homework is all done... Thanks =D

[ironnica]

I was thinking that this was done well from a safety point of view, for another amateur. Kinda explains, done in the back of a uni. Wish my college let us borrow chemicals and make useless vids lmao. well done nonetheless

[E3missile]

so...the further down on the periodic table in the same group the more vigorus reaction with water........huh! i actually do homework on youtube...lol

[crazypianodude44]

haha me too.

[E3missile]

lol

[forever6more]

More fun xD

[jcvhasnoheart]

aww no francium :P lol but well done on GETTING those chemicals

[Noniythegamer]

francium would explode the tub to pieces :)

[ironnica]

If it was possible to get enough francium

[stonefreeJMH]

Throw the potassium in and..... RUN AWAY!

[Keeperz1]

no francium ? :)

[xenocideac]

funny

[xAngelicDemonx]

that is so awesome!!!!

[tstalsby509]

This must not be the sodium metal ive seen, because it makes the water turn either a hot pink or a light pink

[jaxpower1]

that's only if you add an pH indicator, if its just normal water, the colour doesnt change.

[nbaman001]

that is when you put universal indicator in the water to tell the by products of the reaction occuring.

[run3sc8p3r]

i c your american? sul'Fate' :P

[vmelkon]

They don't use metals. They use their salts like strontium sulfate and copper sulfate.

[Geniuskid222]

Beside francium being radioactive there maybe a gram or 2 of it shattered all over the planet.

[CurtisIJM]

Hahaha I know someone who snuck into the school's science store room and stole some potassium, then he put it in his pocket... turns out that was a bad idea, because after he went to the bathroom, washed his hands, and wiped his hands on his jeans, the water seeped through his jeans and reacted with the potassium.. he ended up in the hospital haha :P

(He's ok though, just had some bad burns)

[megtaladeth]

my friends told told me that if i put potassium in my hand and then put my hand in water it would freeze or something. and i did it and it burnt my hand really bad. i just ended up with a few scars tho.

[milroxsox]

no francium?

[sk8trboipyro]

Watch them valence electrons go!

[limeygirl10101]

thanks for the video, it helps with chemistry homework, but what would happen with francium? What colour would it burn?

[KnotsNerd]

Francium.. It'll react HEAVILY with water. Probably break it's container as soon as it makes contact.

[KnotsNerd]

Francium is.. very rare, but it would definitely break it's container as soon as it makes contact.

[spotlightman1234]

@KnotsNerd indeed also because like cesium and rubidium francium would react with air immediately apon contact. dont even try keeping it in mineral oil the dissolved air in the mineral oil would be enough to set it off

[Ridwee]

I don't think they use any of the alkali metals as they're too reactive. I think they use Strondium and copper.

[lolster911]

thanks a lot 4 tht video; it helpedd me with my chemistry homework

[RowShell93]

Do They use Potassium in some fireworks? because it looks like they do

[nico2710]

they use aluminum powder

[PyroCreationZ]

The use Potassium Nitrate (this is not Potassium itself). As for metals, all kinds are used. Aluminum, Titanium, Copper, etc.

[cheeswisz]

my science teacher set off the fire alarm with sodium hahahahaha lollollollollollollol :D

[mieczyk12323536266]

nicely done

@down

Francium is almost unreachable for "home" scientist

[Ben70707]

Everyone Wants Francium,

We've Seen all the rest before Before :(

[Tahoma143]

u should av set the lithium on fire its soooo cool x

[Ryanjoe090]

francium is more reactive that caecium,

i wish i could see it blow up, but there is so little of it :(

[Coleybubble]

Theres not enough francium in the world to do it, haha..

<3 x

[Snakez19]

they all burn down lol

[mingmingnak]

no they were rb and cs because they were liquid inside the ampule.... potassium has to high a melting point to be liquid inside the that ampule also francium was not there because francium is very unstable radioactive element with no more then 30 grams existing at the same time in the earths crust.. so thats why its not shown

[o0MrRobato0o]

where's francium...lol

[nism1493]

the last two aren't rubudium and caesium they're just larger amounts of potassium, if they actually were what they claimed to be, the reaction would be much more violent.

[JoeyMorphinex33]

Can someone please tell me what the smoke is?

Would it be the bi-product of hydrogen or oxygen?

[AutisticWhoLives4God]

Hydrogen, I think.

[Twiztidfr3ek]

its hydrogen, thats where the bang comes from if it was oxygen it would just burn

[JoeyMorphinex33]

These all have 1 shell for the bonding correct?

[AutisticWhoLives4God]

They all have a +1 charge.

[a1t2a3y4]

what about francium hehehe :D

[jamerdude17]

the last alkali metal, Francium, puts all of these to shame. IT IS MASSIVE! but there is only like 5 grams of it on earth and i would not want put it in water if u no what i mean.

[rpacker419]

there's a bit more than that occurring naturally on earth, but we do have synthetic Francium. but even if we had enough of it to create this reaction, it's extremely radioactive, so it would be a pretty stupid idea anyways.

[m6330340]

What really happens is... All ELEMENTS (except for noble gases) need to donate or recieve electrons to become stable, which means having a full outer shell. Alkali metals only have 1 electron in their outer shells. So when alkali metals are in water, their electron goes to hydrogen which needs 1 electron to have a full outer shell. After this happens, the alkali metals are now ions and have a valency of 1+. And since the formula for water is H2O and the hydrogen atoms react with the alkali...

[m6330340]

(Continued)

metals and recieve an electron, they are now a gas and the water is now OH-. So the OH- reacts with the alkali ion which has a +1 valency (since unlike polarities attract)and becomes alkali metal OH. i.e. NaOH, KOH, LiOH.

And the explosion is caused by the burning of hydrogen which is now H2 from the highly exothermic reaction caused(hydrogen is very explosive).

And if you are wondering I am 15 yrs old!!!

[xXxNecromancerxXx]

You have got it right.

[m6330340]

thanks!!! i hope anyone doesnt think i'm a nerd!!! i just love chemistry

[stupidfool91]

the group 1 (alkali metals) are highly reactive this is because they have only one electron in their outermost shell. To acheive stable electronic configuration (full outmost shell with 8 electrons) they have to lose one electron. And guess what hydrogen only has 1 electron on its outermost shell so when hydrogen mixes with these group 1 elements it usually reacts very vigorously. And when you have enough of the substance, it explodes.

[xxfaith0chickxx]

there higley reactive metal the same was as if you add water to hot oil it spits at you this happens

[weeruz]

My dog reacts the same way to water..

[drago2021]

ha ha ha

[Taylor2534]

decay chain for francium

Fr223 -> Ra223 -> Rn219 -> Po215 -> Pb211 -> Bi211 -> Tl207 -> Pb207

[Jlar08]

your all nerds...!!!

[Shankovich]

You have to be a nerd too to look for this video lol, not alot of people know what the group one metals do without a demonstration

[drago2021]

i just came here cuz my science teacher told us to observe the alkaline metal reactions to water for science class... i like the cesium 1 tho (the brainiac thing)

[BanhXeo]

Li + H20 => Li+ + OH- + H2?

[the0lie0that0u0adore]

2Li+ 2H20-> 2LiOH + H2

lithium + water -> lithium hydroxide + hydrogen

[luqmanhakimsuhaimi]

francium mane? kalau ade, mesti bekas tu da melayang

[CaptainNorris]

If Francium could ever be made, it will be only for scntific interests, due to its high mole mass and valence radius, it wont react more violently than ceasium. Theoretically it would be somewhat faster, but energy realease bu that reaction would be much lower.

BUT: the radioactive degradation of Francium is that intense, that some grams of Francium-metal or any other Substance containing the Franciumion, one one point would cause temperatures of several thousands or tenthousand degrees...

[mitchenatorh]

The most francium scientists ever discovered was 10000 atoms. about 0.00000000000000001 grams

[SubzeroFusion]

K (potasium) can be a weak water activated sparkler bomb

[PriceRight89]

Didn't expect the Sodium explosion at 0:56; it made me jump!

[cheesewaffleburger]

Actually Francium has a half-life of a little less then 22 minutes, NOT 0.3 milliseconds.and yes as little as 30 g (one ounce) exists at any given time throughout the Earth's crust.

[coldarcticpenguin]

isn't it like illigal to have it aswell?

[nitrex]

You can't have something that will not exist for long.

[Abbawarrior]

yea it is its a radioactive substance so yea..and with enough of it you could some serious damage so they dont want idiots like us getting a hold of any

[CXRCross]

Do you know what you're talking about? Uranium and uranium ore are totally legal to own as long as the radioactivity is not above 80,000 CPM. All other radioactive materials are legal as well as long as they cannot be made into nuclear weapons (e.g., plutonium) and are not, as stated before, above 80,000 CPM.

[1337BatchFile]

Yes but francium can be man-made

[Magnetohydrodynamics]

Francium has a half-life of 0.3 milliseconds. If you did happen to have a lump of the primo stuff, it would turn to something else in you hands (can't remember the decay path) and you would probably die from cancer a month later.

[SubzeroFusion]

right about the cancer part but wrong about the half-life part

[SubzeroFusion]

right about the cancer part but wrong about the half-life part

[Magnetohydrodynamics]

May i ask why this comment had to be rated as poor comment???

[duckky20]

well... actually francium can be found.. I saw one using it in like a lab... he had special gloves though... When reacting with water it gave a bit of a pink radioactive glow.. it was brilliant..

[jmmatos23]

Are you sure of what u r saying? maybe u r confused or someone fooled u. Maybe it was potassium because of the pink glow.

[Magnetohydrodynamics]

Well anyway... There exists an estimated 15 grams of francium in the entire world... I highly doubt that it was Francium

[coke2]

any idea what francium might even do in water

[jamesfraser92]

francium is so reactive it will pretty much react with any matter. never mind water or even air. no-one has ever seen francium

[nitrex]

Francium is chemically similar to Cesium no doubt.

[jamesfraser92]

what do you mean?

[nitrex]

Francium is no different then cesium, they both have the same reaction rate, however Francium is radioactive and we are talking about a metal that can hardly even exist, it just doesn't exist for the time being.

[ege1993]

people are still trying to extract francium by mixing the elements "gold with oxygen and getting francium and 5 neutrons" they try to collect the francium in a magneto-optic trap, but no weighable amount of francium has been extracted

[nitrex]

Yes but as you see their is no time to extract the metal due to is short half life.

[henw00d]

Francium is no different despite the small fact that it has an extra 32 protons (87) to caesium's 55... that in itself implies it has to be different to caesium... (not to mention the extra electron and proton numbers)

[nitrex]

Yes exactly, you have mentioned my point!.

[nintendowns]

yes its rare and radioactive. too bad, i would love to see its potential.

[XxZipitoxX]

Why does no one every do Francium is it impossible to get your hands on the damn metal?

[DumbledoresArmy101]

yeah it is... its VERY highly reactive... and nearly impossible unless your like a scientist testing this crap to get a hold of it cause its so dangerous

[Skulldaman]

yup theres only 20g of it in the atmosphere and its so reactive that it reacts with everythin it touches so impossible to get.

[Skulldaman]

yup theres only 20g of it in the atmosphere and its so reactive that it reacts with everythin it touches so impossible to get.

[Skulldaman]

yup theres only 20g of it in the atmosphere and its so reactive that it reacts with everythin it touches so impossible to get.
