Elementary Productions: Alkali Metals

[tylerwalker2]

where can somebody like my self get a small amount of lithium that isnt from a battery? i want to try some stuff with it like make my own battery and all that but there is really nowhere that i know of in canada that would ship it.

[zenlikestate96]

you can get lithium foil from those Lithium energizer batteries.

[edottoni]

What about Rubidium and Ceasium ?Obliviusly I don' t have listed Francium, because it's radioactive...

[g3ov4n12]

If you want the small piece of sodium catches fire, just drips some drops of water.

[LeeDwarf]

2:30 (y)

[intercipio]

Your sodium probably didn't light because it had a layer of oxides on it. This happened in my chem class. Finally my teacher got so annoyed that he scraped a big foil like piece off, lots of surface area.

[192asso]

all your videos are beautiful and interesting! Bravo

[getzkazer]

I ♥ the Alkali Metals

[nikkori123]

Awesome video. I'm using it to make up for a lab demo that I missed.  Thank you!

[nikkori123]

[Frresh123]

the alkali metals and the halogens are so great !...

[stanislavo1]

does anybody know where potassium can be baught?

[iseesquares]

need to be a chemist

[22matt19]

go to galliumsource . com they sell all 3 alkali metals seen in this video and they do ship to individuals

[Proudnewfoundlander1]

I remember my chemistry teacher dumped a chunk of sodium in the janitors bucket and it shot across the school

[1930fordman]

how can i buy it

[takuya1095]

I thought sodium explodes in water o__O

[DextChar45]

If you had a pair of tweezers small enough to grab water molecules, would you be able to pick the oxygen atoms from the hydrogen atoms?

[jaguar067]

When you burn lithium will it produce toxic gas that is enough to bring harm to our health?

[robotaholic]

ok lithium iodate crystal

shine a light on it and it will pass thru

brighten it and it will mysteriously glow

that 'glow' shimmers with all the colors of the rainbow

that glow is composed of quantumly entangled photons

i swear tripping on acid, it must be amazing to see quantumly entangled photon glow

i want a lythium iodate crystal ring or a barium borate crystal ring

i was looking for a video of the actual glow from quantum entangled photon pairs

[jheusdens]

lithium isn't the lightest of all elements, hydrogen is, after hydrogen helium an next is lithium.

JH

[denelson83]

But it is the lightest metal.

[jheusdens]

yes i know, but in the video he says at 0:32 that lithium is the lightest element.

[denelson83]

And he's wrong in that aspect.

[mabakken]

I know, guys. I know =)

It has been discussed earlier, but unfortunately I don't have the Original videos any more, end editing would be too much of a hassle! I will add an annotation!

[Masalmeh321]

@jheusdens Actually, lithium isn't the 3rd lightest element, it has the 3rd least atomic mass because it is a metal. For example, Oxygen and Nitrogen are lighter than Lithium for sure.

[jheusdens]

yes, but we're talking about Li the element and Oxigen the element, not about O2 or N2 and not about specific gravity. just the mass of the atom itself and not the weight of the actual substance wich is caused by interactions on a atomical/moleculiar scale.

[Masalmeh321]

If you are talking about the element, then you're right, like one atom each. If its more than one atom, Lithium is heavier. Oh well, we both mean different things. When did you mention that you mean about the element though?

[AHW214]

@Masalmeh321 I thought lithium is lighter than nitrogen and oxygen, its just much, much more dense.

[Masalmeh321]

Honestly, I'm confused =S I think you're right, then again, I don't know what to think anymore. But explain why Lithium is much more dense than N and O.

[AHW214]

If you heated the lithium to a gas form, the lithium would spread out over a large space. The amount of space it would cover would be the same amount of air which you are comparing weight with. So it would be lighter than air and would float but if you turned the lithium gas back into a solid it takes up much less space and the air you would be comparing it to would be smaller. The small amount of air is not enough to make the piece float.

[zenlikestate96]

@jheusdens you are absolutely right, but its the lightest of the metals.

[oldschewl]

Beautiful flame from the Potassium reaction. I had always heard these were violently reactive to water, this is the first time I have seen it demonstrated. Very cool.

[timmyballa]

does anyone know what the new chemical is being made when you put the sodium in water???

[mrdan4]

Naoh sodium hydroxide

[timmyballa]

i thought that was a liquid not a gas

[mrdan4]

yeh the water turns to hydroxide not gas the only gas given off is hydrogen from the sodium

[Dharok60]

where you get the metals?

[sciencoking]

why are alkali metals so soft?

[thedude77777]

wheres the francium?

life of the party..

[UAEchemist]

Francium hardly exists in nature with it's seconds of half life.

[timmyballa]

dude r u retarted rancium doesnt exist in its elemental form it reacts with everything even the air around it if you knew anything about chemistry you would know that

[thedude77777]

k ur cool

it was obviously a joke

but hey

guess not

ur cooler

anyway i got to go get some "rancium"

[Sebbass69]

does anyone know whether it is better to store sodium in amber glass, or in HDPE plastic? I'm leaning towards the glass....

[Ulti13]

Great Video!

Is there a way to make Potassium out of Kno3?

[UAEchemist]

Unfortunately no.

[marioo840]

very very nice!!!!!!!!!

[XGsboty]

omg how much those cost?

[420chazz]

hydrogen is the lightest of all elements. lithium is the lightest of all metals.

[mabakken]

I know! =) It has been commented on before, and I'm sorry for the mistake!

[jamesthesaxist1990]

that's the best potassium + water reaction I've seen!

[bionerd23]

great video! that's a lovely laboratory environment you got there!

[sezyback]

good job! Its awesome to see stuff burst into flames like that!

[keepup32323]

how come the potassium and sodium cause damages to our organism and doesnt have any matter and even being good to health when eaten in banana or coconut? and whats those "downs cells" that SymAmine and you were talking about?

[mabakken]

I'm having a little bit trouble understanding your question, but I'll try my best to answer.

Potassium and Sodium ions are very good for our body (of course not in excessive amounts). Elemental Potassium and Sodium, on the other hand, can cause damage to living tissue because they form a caustic solution when in contact with water. In bananas and coconuts you find the IONS, which are good to us.

A downs- cell is an electrolytic cell that makes Sodium metal, like what you see in the video

[derkozten]

Can't wait to see some Rubidium or Caesium XD

[mabakken]

hehe...don't get your hopes up :P

[keepup32323]

ceaseum?! friendly warning: better use a glass ;)

[SymAmineC8H11N]

why don't you show us how to make a downs cell.

[mabakken]

Well...the answer is quite simple: It is a LOT of work. There are too many components I don't have, such as a powerful enough power supply. Plus, what do you really need a down's cell for? I agree, it is very cool, but its use is actually rather limited. But hey, track down some blueprints and buil it yourself :)

[SymAmineC8H11N]

Plus, what do you really need a down's cell for?> one would need a downs cell to produce anhydrous versions of most of the chemical compounds you had bottled up so conviniently... Also, it can't be that difficult to DIY one?

[mabakken]

Well OK...I'll take that one ;)

If you have a basic understanding in engineering, it shouldn't be problem! I have sent you a link on PM.

[Knirt]

Awesome video. You could have showed how fast Lithium oxides if left out of the oil ;D

Anyway, it's fantastic. <3 Alkali Metals ;D

[frizspin175]

why does paper help sodium to ignite?

[mabakken]

Because the Sodium sticks to the paper, concentrating heat on one place. Or else it just skims around the surface...=)

Funny, you're the first guy to ask! :)

[AVAMagneticlev]

If only we could get these elemnts in AUS even lithum is hard to get.cool demonstation

[jmmatos23]

Lithium is one of the hardest to get, it's even more expensive than sodium.

[vmelkon]

You could at least get sodium from sodium lamps. They are used in street lamps and even home users can buy them. Warning, I've been told some mercury is added to the sodium.

[jmmatos23]

What sodium lamps use is a sodium amalgam, and sodium is the cheapest alkali metal because it is obtained from table salt (NaCl) and as we know NaCl is very abundant.

[crazyboy0602]

at 00:34 you said "lithium is the lightest of all elements" but this is obviously not the case helium hydrogen oxygen are all elements lighter then lithium or am i missing something?

[mabakken]

Thank you for noticing! That is a mistake made by me! What I meant to say was that the Lithium is the lightest of all metals, and obviously not the lightest of all elements, which is Hydrogen! =)

[evansp12]

Excellent video

[Basco36]

cool video

[jmmatos23]

why dont u answer?

[mabakken]

Sorry I havn't answered, been away the last week!

You can probably get them from a chemistry supplier, and sometimes eBay has them for sale. I have sent you a PM on an Internet site that supplies them (if you live in the US)

[dagamezmasta]

I'm not sure that that kid is going to do any good with the chemicals.

[jmmatos23]

do you know a web site where i can buy one fo those metals?
