Alkali Metals: Explosive reactions

[Typhoon10UK]

Imagine if someone made a ship of sodium and they launched it. Would be a sight all right,

[mellamoramonsalazar]

gotta get some cesium and drop it a swimming pool full of people!

[zachandrodney]

step 1 buy ceasium

step 2 get glass jar

step 3 get pill capsule and put ceasium in it

step 4 put water in jar

step 5 put pill in jar of water put lid on jar and wait :)

[MetallicaFan120]

Cesium is one reactive sonuvabitch! That was awesome!!!

[magicman22ish]

thumbs up if VSAUSE brought u here

[Alkatrastic]

MY SCIENCE TEACHER TOLD ME TO LOOK AT THIS MR. D if you read this comment ITS WILL

[seiph80]

There's got to be a way, someday, that man can create a chunk of FRANCIUM... please, God!

[boxxybrownn]

You forgot francium

[pygmypi]

@boxxybrownn Francium is highly radioactive and rare, meaning it's not going to be easy. If you're really willing to watch Francium act in water, then lettuce hope that we will get results. (Punny :D)

[mapleworld777]

what about francium? its even more reactive than cesium....and btw, what would happen if you put it in your mouth??

[WaldoHunter8]

@mapleworld777 I'm guessing it would hurt, but if you want you can experiment it.

[daisyrios101]

Chemistry has suddenly become interesting to me...

[jleer1]

The things I'd like to do with caesium!...

[SomemanAwe112]

@jleer1

Cesium...

[jleer1]

@SomemanAwe112 Actually, both spellings are accepted - and caesium is more accurate. Search google.

[SomemanAwe112]

@jleer1

k then

[cheat12code]

0:33 -- I thought that was skype o_O

[Shaosprojects]

I can hear someone whistling at the end of the video.

[weedpussymoney321]

remmeber we had 2 watch this i science class, but i was eating cheesy bread so missed most of it

[vladissimo18]

Franciu it's extremly reactive

[rumnah100]

what did you throw in water befor caesium..

[shinenight]

Awesome!! Imagine if you throw the last one in a toilet

[smileyking96]

1:00 FIRE IN TEH HOLE!!!!!!!

[MrSkinnyBill]

We watched this video in Science earlier.

My science teacher is wondering why they threw a test-tube in the bowl without mentioning it at 0:56

[PCPicklePC]

@MrSkinnyBill It's because alkalai metals react with oxygen and water in the atmosphere so they are typically stored in ampules (little glass test tubes that are vaccum sealed) which are broken only when the pure element is needed. I'm guessing that's what the test tube you saw was, and they did it just to react any left over Rb.

[Deel2506]

Tha narrator sounds like Eric Idle :)

[lonelyangel36]

Oh my shit! >< lol this is cool. 

[42Mrchadman42]

I wonder what would happen if they used francium?

[liamzuid]

What makes these things react to each other?

[liamzuid]

What makes the one alkali metal react better with water then the other?

Is it the amount of protons and neutrons in the nucleus of the element?

[Aviatorsmith]

@liamzuid The alkali metals get progressively more reactive the lower down the periodic table they go. Their reactivity is due to them having only one valence electron which is easily lost. The reaction occurs when this electron is lost. As you progress down the periodic table, the metal has larger atoms. Since the electron is now further away from the nucleus, it is more easily lost and the reaction occurs at a greater speed.

[surajmself]

awesome !!!!!!!!!!!!!!!!!!!!!!

[genelin1995]

I just want to see what happen to caesium, I just have to see it since the teacher does not allow us to see it.

[chemnuke]

@genelin1995 It's really expensive for just a few grams of it. There's better places to spend that money.

[TheWhistlingCysts]

yo, put this metal in water make some steam turn some turbines for infinate energies and moneys

[GodlyBoss]

1:05 LOL. O_O''

[concealedknight]

osama bin laden would be skilled in chemistry

[Puzzlaholic]

I want some cesium!!!

[necroheartplucker]

No wonder cesium is not allowed in school laboratories. It makes the glass basin go KABOOM!!

[RaynaKenadi]

actually.. im sixteen. just the sound it makes is the funny part.. compared to all the other ones.

[RaynaKenadi]

i got shown this video in my science class.. and after the last reaction i couldnt stop laughing for about 20 minutes xD

[fizzletto3]

@RaynaKenadi But... why? It's not funny... unless you're like 13...

[morningsnazzer]

holy shit! that last reaction was awesome :)

[silentbl00d]

ending reaction-

holy shit!!!!!!!!!!!!!!!!!!!!!!! ahahahahahaahhehehehehehHAHAHA­HAHAH!!!!!!

HHHMMM THAT SOME GOOD STUFF i dont know why it cracks me up.... =/

[chillz27]

the should make bullets out of cesium

[bfg123HELLO]

sooo... is everyone here cuz of chemistry course work in school on the discovery of francium and alkali metals then like me? xD

[htf5555]

@bfg123HELLO i came here for splosions

[SuperLbptutorials]

@bfg123HELLO lol i geus so 

[TheMattysamson]

@bfg123HELLO No..... I'm here cuz this what i like to research in my spare time...... :P

[twixas8866]

sadly there are no videos of francium touching water !

[pcmarriotthk]

CESIUM WIN!

[Sajjadkhan456456]

there is no option to show how does alkali metals react with hydrogen?



[fadougeful]

No need to show francium.

[Jaamesanator]

@fadougeful its impossible, francium is so reactive it reacts with only oxygen instantly. hence why there is hardly any francium because it is so difficult to make and keep. idiot

[Aviatorsmith]

@Jaamesanator The reason why francium is so difficult to make and keep is only very partially due to its reactivity. The main reason is due to its large atomic mass. This causes its nucleus to be extremely unstable and have an extremely short half-life. It basically decays before a large amount of it can be collected.

On a side note, don't you think that calling him an idiot is a little harsh? Your response wasn't the correct one either and i'm not calling you anything.

[artemis101814]

LIKE!!!!!!!!!!!!!!!

[najee131]

lol :)

[KikaruHatsuharu]

last one was the coolest :D

[johncena1097]

good iuse it at science

[MacOSXHD]

why does this happen?

[airrocker001]

I fing this extremely amusing, especially when the guy whisltes in the end lmao

[Pikanyaasan]

Does this guy sound like the Monty Python narrator to anyone else?

[gabeuop79]

WE NEED FRANCIUM !!!

[MrBlurtit]

@gabeuop79 Not likely as it's radioactive and extremely dangerous :P

[gabeuop79]

@MrBlurtit - - Ya, of course you're right. On a side note, the next synthetic element to be created (if we create one after Ununoctium, which is element 118) will fall under the alkali metals group (beneath Francium). Theoretically, element 119 would be even more reactive than Francium. This is extremely unlikely however, as the new valance of electrons would be extremely unstable - producing even a couple atoms would be a challenge. Fun to think about though...

[dclleyshon]

LOL anyone doin science HW ? lol ...?..??

[MiShaXVI]

im surprised they actually tested cesium that close up. must have been a very small amount...

[mymomrocks8]

@MiShaXVI It looked to be about a gram

[JordanAndJarettShow]

for a sec at 1:04 I thought the hand was bleeding

[dspeev8]

oh my lord my teacher showed this video to us in science and i about peed my pants at cesium

cause i called it im like its gonna be a bomb...

[AYoshiTale]

Theres another one called francium, but its so dangerous its never used

[volleygurl634]

yay science



[volleygurl634]

we did this at skool and it exploded se we had to leave the school yay learning

[ballen900]

DAMN

[booksandvideos]

Francium would be too damn expensive to obtain with today's technology. it would probably cost a few hundred thousand dollars to obtain a gram of it.

[MasterTonberryV1]

@booksandvideos

Few hundred thousand? No, few hundred millions or some billions.

[darkace355]

@booksandvideos fyi you cant buy francium because it's so rare

its priceless

[booksandvideos]

@darkace355 A little bit of it can be made in a laboratory; it's just really expensive to make.

[mymomrocks8]

@darkace355 if you gathered up all of the Francium in the world it would equal to approx. 1 gram, give or take.

Still, it would be nice to just get a huge 1 ton chunk and heave it into a lake. *dreams*

[darkace355]

@mymomrocks8 umm yeah

it would be a waste of francium.....

[mymomrocks8]

@darkace355 but a hell of a show....

[ijunkie]

The most stable isotope of Francium is 22 minutes if I'm not mistaken. There is only 30 grams of it in the Earth's crust at any one time, from the decay of natural radioactive elements. If enough of it could be gathered to form a pure sample, I have no doubt the reaction with water would be explosive, much more so than shown here with caesium.

[mparker711]

Francium has a half life of 22 min so it is possible to actually get it in to a small container of water for youTube viewers despite its radio activity, however more precautions will need to be taken to make that happen. so who ever did this video was just to lazy to do all the crap that needs to be done for Fr

[cfranklin85]

fuckin awesome!!!

[endimion17]

What a waste of huge and expensive pneumatic trough.

Yet I can't believe the "OMG francium"-dumbasses infested even this video.

[Devin6gw]

lol if they put it in coke

[LiamHDx]

@Devin6gw lol

[JeffIsJello]

I lol'd during Cs for some reason

[harpellk]

where can i get my hands on this stuff.... forrr science of course :D

[IndiePharm]

I can't imagine what Francium would do, considering that only 20-30 grams exist in Earth's core.

[DrIntrebec]

i like cesium!!!!!XD!!!!!!!

[tm312th]

....chemistry is a bit....boring 2 me but i like watching EXPLOSIONS! :)

[elcochipit]

Nice video!

Do science or die!

[dialga1788]

@elcochipit exactly! science rules! That last metal went like BOOM! rofl

[drewkipow]

potassium looks so cool when it reacts with water!!!

[daoldGNRrox]

this is gay. fuck mr workman

[psychohitler]

@themadmoose16 ive always hated doin balanced equations lololol...

[GothicSilverWolf666]

OMG EPIC!! we just learned about this in science and me and my friends wanna try this over the summer.... does anyone know where to get a good amount of any of these elements pure? Perferably the one with the most violent reaction possible ^^;;

[spotlightman1234]

only a very trained person who is familiar with their properties should try any of these reactions.

if you are going to try these reactions Wear Protection goggles or a face mask and gloves. second the alkali metals all react with air and its possible for them to spontaneously ignite in air under the right conditions. third cesium and rubidium usually run for about $150 a gram.

and potassium and sodium around 50$ and lithium can be found only in Energizer ULTIMATE lithium batteries.

[hacktgs2]

@GothicSilverWolf666

And i hope you do serious damage to yourself if your going to do something under unsupervised conditions, or without safety precautions.

[GothicSilverWolf666]

@hacktgs2 haha well yeah we're a group of stupid teenagers with nothing else better to do than explode things but we're gonna wear like safety goggles, protective clothing, heavy duty gloves, ect. AND we're gonna chuck some in water and run for our fukin lives XD we're not dumb enough to stay around for the aftermath ^^

[hacktgs2]

@GothicSilverWolf666

That would have to be the longest fucking sentence I have ever seen.

[MasterTonberryV1]

@GothicSilverWolf666

I'm sure Lithium, Sodium, and Potassium could be bought almost everywhere. For Rubidium and Sodium, they're sold in some raremetal categories, within a price range of $35-$60

[MasterTonberryV1]

*Rubidium and Caesium, goddamn my typos.

[mazdark]

WOAH CAESIUM WAS AWESOME! :p

[GingerEilish]

Thats is funny lol :P Love the last one!

[jonboy7777]

erm why do alkeli metals react this way? something about the electrons in the orbitals?

[Sootsootles]

@jonboy7777 yessum. Electrons on the outter orbitals sometimes need more friends as they think 8's a party. So take lithium, theres a very bored lonely electron on the outter (Valence). For water theres 7 on the valence, the valence prefers the party number 8 so that one bored electron is jumping ship and hitting Ibiza for all night partying. This in turn, creates reaction. And sometimes as seen, could be a hell of a hangover =)

[HollowNofal]

all the alkali metals has 1 electron in their outermost energy level(valence shell or energy level), as we go down the group, the attraction forces between the valence shell and the nucleus decreases, thus it's easer to loose the 1 electron in the valence shell. as the alkali metal reacts with oxygen in water, hydrogen gas is released which catches on fire, and it's well known that hydrogen reacts explosively with oxygen in the air

[nairdajun]

yes because it has so many orbitals its highly reactive because it only has 1 electron in its outermost shell so it will do anything to stabilize that negativity even if it means pulling off hydrogen from water..even for such a strong bond like h2o

[facatra]

If u can answer this question then ur good in chemistry lol don't look up on internet or so(maybe stupid question)

=In what is Sodium keept with?I know in a bottle or so but wich liquid?

[ragingvirus78]

its kept under oil

[facatra]

@ragingvirus78

its kept in petrolium

[HollowNofal]

lithium through potassium are kept under oil, ceasium and ribidium are kept in vaccum tubes :)

[psychohitler]

hope one day technology and science can progress to a point where they can actually obtain a feasible amount of lasting francium so that they can throw it into some puddle... lololol that would be one hell of a reaction hahaha...

[Xenophobia777]

@psychohitler And I hope that you will find something beneficial rather than destructive to science.

[Celeb132]

@psychohitler OMG! YES!

[physicmad]

@psychohitler BOOOOOM!

[cybernike3]

@psychohitler But the amount of energy that is needed to generate enough francium is more spectacular than the energy given off by the francium reaction with water.

[psychohitler]

@cybernike3 well in this modern society that embraces new ideology and open mindedness, entertainment has now branched out from large scale industries like movies and music to those small short videos that someone make or happens to catch while doing something simple routine. example, simple fail videos XDXD besides curiosity makes us do unreasonable things.... like using all our knowledge on science so we can somehow obtain some francium to throw into a bucket of unlucky H2O molecules XDXDXDXD

[OrlandoKidd]

@psychohitler rofl ikr, francium catches fire just from moisture in the air or oil it's stored in.

[darkace355]

@OrlandoKidd its not francium

[0tni3lMndZz]

@psychohitler i would bring some francium to school on a rainy day.. and Kah-boom!! ohh! there goes my teachers car!! lol

[CadetGrant]

@psychohitler I think it would make it where they would be able to make tsunamis and blame it on natural causes xD

[ImAnotherZang]

@psychohitler damn now you gave Bin Ladin an idea....lol

[MegaLalablahblah]

that really makes me want to make a ball of cesium and throw it as far as I can into the ocean. haha *fwoosh....BAM!*

[ImAnotherZang]

@MegaLalablahblah No more skipping stones. We skip Caesium from now on!

[MegaLalablahblah]

@ImAnotherZang Oh yeah we do! We could market that idea!

[ImAnotherZang]

@MegaLalablahblah No hell no we should shut up right now I just saw Bin Ladin with a flash in his eyes and a lightbulb on his head.

[MegaLalablahblah]

@ImAnotherZang Haha! that was funny

[ThePhoenixwings]

EPIC :-)

[waybogus]

What happens when you put these elements with fire?

[19andoverlol]

@waybogus

Oddly, nothing at all. The only reason they explode in water is because they react with the water to produce hydrogen gas and a lot of heat, and the heat produced ignites the hydrogen produced and an explosion occurs.

[2012rcampion]

@waybogus: Well, since the heat of the fire would drive off any water, this type of reaction probably would not happen.

[ultrachemist13]

they catch fire.

[JohnSopesor83]

I think, it is no efficient to use in military munition.

[kavanagh21]

Don't be ridiculous. Cesium is not a "military" compound nor is it illegal to possess. It's got many commercial uses. Google it.

[Riftcast]

You've gotta admit, though; if we had a bit greater a supply of raw cesium, I bet they could make one hell of a conventional explosive with it...

At the least, one very, very powerful depth-charge.

[Qwerty48121]

thats highly unefficient as octol does a more terrifying job... just not with water

[Riftcast]

@Qwerty48121

If we had a lot more Cesium on planet Earth, I think the possibilities for an explosive packer like cesium chlorate would be brilliant!

I'll give the torch over to octol, though. What a violent cocktail of explosives.. O.O

[MarioLuigi141]

that glass got pwned with cesium.

[luvwrapper]

How did they get a hold of cesium, It's military mineral, its illegal to hav even possetion on the metal. even a thumbnail size

[takamichinuku]

I want to get a hold of some of these metal :)

[flagman57]

its very expensive

[takamichinuku]

can u give me an idea? How much for a gram of the more rare ones?

[flagman57]

i would say about 30 to 60 dollars for a gram of cesium

[JMP98251]

Cesium is about 85 euros per gram (99.5% pure)

Rubidium is about 105 euros per gram (99.6% pure)

But they are hard to come by, though in most countrys it is not illegal to posess the metals.

prices per gram decrease a lot when you buy more.

[soldatojoker85]

CESIUM?!?!?! it's radioactive!

anyway francium is the rarest element...

i'm sorry for my english :)

[flagman57]

its not radioactive. at least, the most common isotope isn't

[Brianthehax0r]

Dam I was hoping for some massive Francium explosion :)

[meteorman96]

thats really cool unfortunately, we cant use francium because its radioactive, costs a crapload to get, im talking billions to get a visible quantity, the explosion would kill anybody near it, and the half life of its most stable isotope only lasts 22 days

[takamichinuku]

cool facts

[meteorman96]

lol

[flagman57]

no. i think its 3 hrs actually

[thomashusak]

Francium is radioactive... and almost impossible to get even a few mg. for a demo like this

[OyVeey]

@thomashusak More accurately, all isotopes of francium have incredibly short half-lives, and there are likely no more than a few grams in the surface of the earth at any time, all released as a byproduct of the decay of thorium and uranium. All videos you see involving francium are fake.

[cylaucool]

why don't use Francium

[rylangel]

@cylaucool You saw the reaction between the cesium and water, right? Think that only bigger if you were to use francium.

[410Tifo1]

the last one Rocks(6)

[Lordiranger]

Wow this is so awesome!!!!!

[elouephaley]

potassium is always my favourite

[kevl4r14]

You can hear a whistle at the very end XD

[sliderblue1992]

yeah i heard that lol

[haoyuan93]

what the hell did the guy throw in when the rubidium was reacting with the water?

[vitorix24]

LOL

[MrPcmaker]

with lithium in the lithium batters would be the same ?

[Shade32199]

@MrPcmaker yes, but the lithium is contained in other metals

[InvaderSkat]

Everyone in my class took a shit on ceisium XD we loled so hard when our teacher showed us this XD

[H2Zman]

mine too. If you have ms. Lawrence 8th period that would explain why, though I doubt that coincidence...

[RepEvox]

Novato?
