Francium - Periodic Table of Videos

[darkrider411]

Dude I love his tie!

[GreenHandMovies]

So did a small lightning storm pass by your head or what?

[CodCats]

Why couldn't he have written my Chemistry Exam.. Fuuuuu!@!

[Darkus1056]

i was looking for the song francium... :L

[Devantium]

oh mY GOD HIS HAIIIRRR

[JossJossJoss1]

Wikipedia - Francium was discovered by Marguerite Perey in France (from which the element takes its name) in 1939. It was the last element discovered in nature, rather than by synthesis.

Last element discovered from natural samples, rather than smashing shit together at a bajillion miles an hour in enormous mad science fiction experiments. Iiiiiiiinteresting

[johncerasi]

I refuse to die until I see Francium react with water. I don't care if it kills me. 

[MidgetRage666]

@johncerasi its probably would

[OprahBangBus]

@johncerasi

Be prepared for a long life... If I recall correctly, Francium does exist in nature, but due to its radioactivity as stated in the video, it decays into other elements quite rapidly. As such, it is theorized that only a few grams of the substance exists on Earth at any given point in time. Even more disheartening? It isn't some little lump just waiting to be dug up; it's a few atoms here, a few over here, and maybe a smattering over there. Not a lot to use for a reaction.

[antiHUMANDesigns]

How can this video be so awesome? :P

[MrAwsomehair]

The way he moves his hands is so distracting yet i listened to his every word 0_0.

[FifaComunity]

You just done my homework, thanks :P

[MrMeat42]

You got my vote up when you said "Alkali metal tie"

[niggergotswag]

Huh, I wonder how Francium Astatide would react with hydrogen alone

My guess

FrAt + H=Nuclear Explosion

Just showing off my knowledge of combustive reactions since I feel so smart today. Just learned this in science.

Cesium Chloride + Water=Explosion

Potassium Carbonate + Unuhexium=Explosion?

Uranium Phosphide + fire=Explosion

Radium Sulfate + Plutonium Bromide + 2000 degree fire=Explosion

either that or it'll poison ya. :)

[SgtThehunted]

Water+Potassium= Scientist hair

[pitomba125]

@06hurdwp Dude, there is barely enough francium in the world for you to see. It has only been synthesized once and it was in gas form.

[06hurdwp]

@pitomba125 no we had like 1 kilogram of it in class

[pitomba125]

@06hurdwp No, you had cesium. not francium

[123ElTri]

It seems to me that he has a case of parkinsons disease because he shakes alot . Just saying , nice video; very honest man.

[stubs13]

Which metal makes for the best dildo?

[tomsta117]

@stubs13 Neon.... Jackass

[SgtThehunted]

@tomsta117 Neon is a gas.... Jackass

[tomsta117]

@SgtThehunted I was being sarcastic.......Jackass

[jleer1]

I'd be too scared to put it on the tie.

[TheDavid559]

that guys hair exploded

[95operation]

he's like the ideal grand father!

[xredb]

this guy gives out way more facts about chemistry than my teacher does..he's reaaly cool in the sense that he can relate chemistry with history

[racoon965]

this guys voice would go great on audio books. thumbs up if you agree

[mrtrollosus]

i LOVE his tie :D i want to meet this guy in real life :P

[xvancexable]

This person would've made anyone love chemistry.

[fireice2037]

If i had a teacher like this guy i would of payed more attention in school!

[034839451]

i like this guy too much

[thejellyfisha]

i love this guy

[worldgameswwe]

nice video learned more

[parkerusc]

this guy is my hero

[HappyMunky1087]

holy crap. did anyone else catch that? the man was being HONEST. he only speculated and made it clear he was speculating. he didnt try to act like he knew something he didnt. now if only we could all be like this

[XAttaHabibX]

@HappyMunky1087 Yeah I noticed That too. I that was me,(and I am DEFINITELY no expert) I would've said "no one knows" instead he said "I am not sure if anyone knows". Humility at its finest.

[721tomato]

francium is extremly rare and only 30 grams can be natrually occuring at any given time on earth the most that heve been created in an lab was 300 000 atoms not even visible to the human eye

[kitty6837]

@721tomato Also take into mind the extremely short half-life of Francium, which is only 22 minutes, or so I have been told.

[pman5595]

a red liquid metal that explodes in water? Want.

[dddddddddddd71]

thanks i finally got a fucking answer and not some gay ass fake videos

[AokiAisaka]

I can't believe how awsome the old man is, i mean who wouldn't want a tie that has the alcaline metal on it???!!!

[Aviatorsmith]

@vgreviewonline By TNT, I mean the energy to mass ratio of TNT ie one ton of francium is equivalent to one ton of TNT. It should be in that range.

[DevilMaster]

@RomanianSpetsnaz Is it just me or does your question lack a pronoun?

[Aviatorsmith]

@vgreviewonline It will not be like a small atomic bomb. You have to remember that when it reacts with water, it is overcoming the relatively weak Electromagnetic force while in an atomic bomb, it is overcoming the extremely strong Strong force. The energy released is not comparable. It would most likely be similar to TNT at best.

[unholysanta]

laser beams death rays lightsbaers HA i have a francium fusion reactor. 20 pound lump of death here WE FUCKING GO

[osufan3535]

i really wanted to see an explosion

[heath780391]

i love his hair style! LOL!



[dudeguy927]

ohhhh if I only had Francium....

[MozartJunior22]

25 people were expecting to see a francium in water reaction.

[tylerintheshadows]

Thumbs up if you know what happens when you mix francium with water lol ;)

[YooEssBee1]

Epic Hair

[eteddy0]

yay learning! :D

[lizziebug123]

This man has purely theoretical hair. You can almost see right through it. This is how all scientists should aim to look :) Thanks Mr Scientist man.

[rspwnerful]

@lizziebug123 his name is Martyn Poliakoff. Just figure you wante to know what "Mr. Scientist mans" name is.

[Adimanstudios]

@RomanianSpetsnaz HOLY SHIT 350 THUMBS UP?!?! :O

[CatchingElectricCity]

Anyone else think "hatsune miku" when they watch this?

[hanfernparkour]

There are 25 people who want to study Francium for very long period of time

[YoshidoriAnimation]

I clicked this because I thought it was a joke when I looked at his hair....

[firefish821]

im francium my mom says im am

[joshpeace23]

I've only experimented with potassium and lithium in h2o and they produce a hydrogen gas do all alkali metals produce the Sam reaction and if so would the gas from francium be radioactive .

These videos are great

[somethingconveyable]

@joshpeace23 The Hydrogen gas released from the reaction would not be radioactive, however if Francium (g) was present it would presumably be radioactive. The Hydrogen gas released from the reaction is due to the fact that the Alkaline metal in question, in this case Francium, binds with the Oxygen in water (H2O). This creates an Akaline Metaloxide.

[somethingconveyable]

@joshpeace23 Rust is a Metaloxide with Fe, known as Ferrous or Iron.

Since the Francium has binded with the Oxygen in the H2O and not the Hydrogen the left over Hydrogen is.. well left over and floats away (or is ignited as is often the case).

[t3hsniper]

@joshpeace23 I would bet the reaction would be explosive like that of cesium. You should watch the related video "Alkali metals in water, accurate!"

[xshoreLS1]

After learning a little about francium, I'm wondering if there are other elements formed in supernovas that exist for only a short amount of time. I wonder what unusual and usual properties they would have.

[LuxuryBarrage]

Ununennium in water.

[Maetel22]

@LuxuryBarrage annihilation Jim. total, complete, absolute, annihilation...

[mynameaborat993]

so fucking cool

[Darkskully70]

Can you be my science teacher please?

[FierensM]

Awesome fro

[TheBeastGuy6969]

nice hair bro

[cyfer911]

" Youtube video fo the century". I laughed

[thesidewayzone]

Great Scotts!!!

[egodamonra]

I feel sad that some of the worlds best chemical scientist have not even seen nor touched all the elements thy learn and know things about. that would be like being a water expert but to have never seen the ocean yourself.

[kurtilein3]

@egodamonra

chemists do spend time in labs, and when you study chemistry, you get to see a LOT of elements. And chemistry labs have plenty of elements stored.

Francium is tricky because its so radioactive, you have to artificially create it. and then it has a very short half-life, it quickly decays into other elements. a half-life of 22 minutes at most means that it cannot be stored or transported. creating enough of it to see it with the naked eye is a huge quest.

[joopie99aa]

@kurtilein3 Exactly! As the matter of fact, it is expected, that at any given time only about 30 - 40 grams of Francium is spread out over the entire earth. The largest amount of Francium ever created in a lab, was 300,000 atoms. That may seem like a lot, but it is only 0.0000000000000001115 grams.

[blenderpanzi]

A question: Why has the periodic table the shape it has? And why this strange extra piece?

[TrophicFault]

@blenderpanzi It is shaped in the it is to describe the orbital shells in a neat way. By "extra piece" I assume you mean the elements separated at the bottom. Those are synthetic elements, which are not naturally occurring.

[MrJimmy9800]

@TrophicFault The elements in each row tend to have the same or similar chemical properties. The separate section is a different type of valence electron shell and there are naturally occuring elements there (such as neodymium). However element 92 (Uranium) is the heaviest element in this section that is naturally occuring and the heavier atoms than that are all synthetic (as far as physics/chemists know) The periodic table is really a shortcut designed for figuring out chemical reactions.

[FacepunchForums]

Great scott!

Gordon freeman!

[JakiiB]

Great Scott!

[Fullmetalminos]

@AgentCROCODILE you forgot Alkaline EARTH metals tie, lanthanoids' and metalloids'.

[victorivbf]

Who clicked this video when was watching Miku Hatsune's Francium?

Thumbs up ^^

[cherrybabe121]

@victorivbf Awh yeah~

[sreychresse]

i was hoping to see francium in water

[angelxsid]

@sreychresse It's the 2nd rarest element in the world, mere grams.

[sreychresse]

@angelxsid ano =[

[cristianfcao]

"You can't get a nice lump of francium of the sort of size that you'd like to throw in water to make the Youtube video of the Century".

LOL That's indedd a pity!

[Versudan]

I still want to see a 2 kilogram lump of Francium dropped in a swimming pool...

[missemilena]

who has a reactive metals tie except this guy? :)

[strange6]

I've no doubt he's a nice enough chap but he isn't exactly interesting.

[strange6]

Science teacher? Hope you're joking - he would send me to sleep

[MrUltraSuperMan]

@strange6 dont they all...

[greatwhitenorth112]

@strange6 you have the brain of a mule

[strange6]

@greatwhitenorth112 I did Chemistry at Liverpool and really enjoyed it. This guy would just send me to sleep. And judging by your redneck homepage, I find it quite funny you should be refering to my brain when it's clearly obvious you don't possess one yourself! lol What a retard you are :-)

[greatwhitenorth112]

@strange6 explain the electromagnetic spectrum to me then

[AmphibianStudios]

@greatwhitenorth112 dude that response just showed you how smart you are.....referring to high school chemistry. GOOD JOB.

[tomino3093]

funny guy :D

[BlackSphinxGG]

I don't think the reaction would be catastrophic in Francium would be dropped in water. Most likely would look a lot like Cesium, but a bit more energetic. But since getting a lump of the thing is impossible right now, I guess we can only guess.

Also, being so darn radioactive, I wouldn't want to be the one throwing it in the pool.

[DactaDork]

Awwwwww... No more alkali metals? NOOOOOOOOOOOO!

[BubbaHoggit]

France has TWO elements named after it? Those greedy little...

[DevilMaster]

@BubbaHoggit My Chemistry book says that Paul Emile Lecoq de Boisbaudran, the discoverer of gallium, named it after himself. "Le coq" means "the rooster" in French, and "rooster" in Latin is "gallus".

[SuperTechieJ]

Was that a Windsor knot?

[caitrossfluffy]

This guy is awesome lol :L

It's my lifetime ambition to see a reaction of Francium with water, but I know it is destined to remain unfulfilled. *sighs*

[Matisyourmaster]

okay the reason no one knows what colour francium is is because only 30 grams of it exists in the earth's crust at any one point and it has a halflife of 22 minutes. It can be synthesized by combining gold with oxygen and through this method, the greatest amount of francium that has ever be viewed in one location was about 300,000 atoms worth

[MyMadChemist]

I believe there is only around an ounce of naturally ocurring Fr in the World at any point.

Does anyone from the team know what the pKa of the hydroxide would potentially be?

[ChibiVamp232]

See? That is the hair all scientists should have.

[amelialxp]

I want his tie XD

[oOIIalexIIOo]

And people say not to stereotype...

[WhoisJacqueFresco]

@Adimanstudios Just remember some of the best teachers you will get are at the universities. So go through the bs at school and enjoy the best teachers at your university.

[Iamcartmanxd]

@Adimanstudios The likes are a 420. Imma leave it that way.

[Adimanstudios]

@Iamcartmanxd OH SHIT 420 LIKES??? WTF!!!!!!!

[ionnieboy]

@Adimanstudios

thats gonna be one full class room :/

I think ill join. :D

[Siisandor]

It's cool.

Are you sure there isn't any information about Francium's colour available?

webelements(dot)com/francium/

There kindof is some information available, but nobody knows for sure.

It's interesting. I love Chemistry.

[kapwul5]

that tie is awesome!

[obiwan88]

Lovely chemistry lesson there from the gentleman here, pity he wasn't properly introduced here. I'm sure many young minds are already inspired to like Chemistry a little bit more by this video alone. I know I am, though I'm not exactly a young mind. ;-P

[scraffs224]

Hes so cute.

[iBlogify]

This helped I'm doing alkaline metals with water in chemistry!:)

[Mistercharming]

I LOOOOVE white people fros. LOL!

[monsterrun]

my bad mesons are used for stabilizing the bombardement of francium in case of over heating.

[monsterrun]

to make francium 223 you need thorium and isolate in in a low gravity controled room.

and then bombard the crap out of it with protons until francium 223 is produced.

afterward i know that francium dosnt live long. so you mass as fast as you can francium 223 and put it in a 0 gravity room.

and bombard it again with polarons. to get the secret governement AEE.

They called it Mesons according to the illuminati, but AEE stands for Alien Energy Element. sumething like element 360 but not sure.

[Alohomorafication]

Ha...a white guy with an afro :D

[AstroChickenII]

What about the people who discovered francium. They must have seen what colour it is.

[benjojo12]

@AstroChickenII They made a few atoms of it...

[god0fgod]

Typical scientist bloke. He needs a bow tie though.

[STEVEGET]

@god0fgod yep, and a pen protctor, lol.

[PaladinswordSaurfang]

how is francium more radioactive than friggin plutonium? radioactivity generally increases with elements of higher masses, so francium, which has an atomic number of 87, should be less radioactive than plutonium, which is 94...

[agrosanta99]

@PaladinswordSaurfang Franciums half life is alot higher than Plutoniums. It gives of more radiation in a shorter time. But due to this, framcium hardly last long enough for anything to be done with it. It'll be gone within minutes of coming into contact with air.

[PaladinswordSaurfang]

@agrosanta99 higher half life? half life isnt measured in height idiot, and if the number were higher, then you would mean francium has a "longer" half life...

[flopski]

@PaladinswordSaurfang

Francium isotopes have halflife times ranging from 3,0 to 21 minutes.

The halflife time of the most radioactive plutonium isotope is 14 years.

Francium is about 2 million times more radioactive.

[sfak94]

the government probably has barrels of francium and thats y theres not of it left

like oil, francium was there but now its rare

[Gray6584]

Hey guys don't make fun of hi he's 40 times the man any of you will ever be.

[XxDrD34THxX]

Something tells me he gets no pussy...

[DeepAbsentia]

@XxDrD34THxX Maybe it's something connected AND proportional to "something tells me you can't get any laughs"

But that's just a wild guess

[jamesthejerk1]

Disco Stu likes Francium.

[frankjohnson123]

My favorite element!

[bajer111]

tie-logic ftw

[bensiemaszko]

I dont think he was waving his hands about enough

[mryantao]

Wow alkaline metal tie! Splash some water on him to make him look more like Einstein!

[WyattKudo]

This guy's hair proves he knows science.

[steviebear]

this guy looks like the crazy lady from the morgana show!

[megamarko94]

Biggest amount of francium produced in lab is around 300.000 atoms.

[Sam66king]

Thats some crazy hair you got there bud

[ScottSkye9500]

Martyn has some crazy ties

[TheLordZixx]

I love how he has a tie for everything :D

[theMANsiontv]

i am brown

[MidnightRedemption]

hey, can anyone tell me about the extended periodic table?

[wacko031290]

@MidnightRedemption They did a vid about it try there

[Maetel22]

a liquid red metal, i like

[northenswede]

I've read that there's only 15 grams of Francium on the entire planet

Not that much really

[tkdojo]

@northenswede only about 1 gram actually not much at all

[Teankun]

That's right. Cesium will melt in your hand. Shame francium is too unstable. Maybe. I always wondered if it inwater would make a small nuclear explosion

[Skittles1622]

It really kinda sux that francium is extremely unstable cus I wanna throw it In a pond :(

[shadowblack1987]

Ebay.fr... Search: Francium... awww ebay fails :(

[nybotheveg]

very interresting :P if it had an experiement it would definantly have been the video of the century ;P

[jamirequez]

ghiblade are you saying that reacivity increase as you go further left on the periodic table, saying that gold is more reactive than flourine? i think not

[klspore9708]

@jamirequez I believe he is saying that the reactivity of metals increases as you travel left on the periodic table. Therefore, Fluorine, being a nonmetal, is really quite irrelevant to his point.

[MrShadowlord671]

the military knows all about francium... those bastards

[Alphaforce100]

What's the reaction at :37? Please someone help me...

[gennaman2bit]

@Alphaforce100 2K + 2H2O => 2KOH + H2

[Alphaforce100]

@gennaman2bit so i have one more question u saw how it separated in to pieces and it made trails of smoke wud i get the same exact reaction or was it just by chance

[gennaman2bit]

@Alphaforce100 trails are producted because Li Na and K are lighter than water, so they float on it and the explosion is produced on the surface. Rb, Ce and Fr are heavier than water, so they esplodes in deep.

[95nwot]

@gennaman2bit Type PRIZE before youtube

[ilvmusiclol]

@gennaman2bit they are not lighter, not in the sense you mean, any of these metals are lighter than water in the amounts you would want to react with it, the reason they float is because Lithium, Sodium and Potassium are all less dense than water, meaning they simply float on the top, however, the reactions that occur between alkali metals and water is often too fast to notice this.

[gennaman2bit]

@ilvmusiclol language mistake sry, i said lighter, i meant to say less dense. U can always notice the reaction because all alkali metals but lithium do explodes in water.

[Oliver4888]

@Alphaforce100

The reacton is at about 0:37-0:39

[Alphaforce100]

Please someone help me. is that water with Potassium at 0:37?

[Oliver4888]

@Alphaforce100 yes

[aprilhareau]

This video should be upgraded to show the updated caesium reaction (much more impressive!)

[lolimnoteighteen]

if you know a thing or two about chemistry, this professor is pretty retarded
