Elementary Productions: Alkali Metals

The three first alkali metals are: Lithium, Sodium and Potassium. These increase in reactivity down the periodic table.
In this video, physical and chemical properties are demonstrated.

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

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!

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!

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

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

[denelson83]

But it is the lightest metal.

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.

[zenlikestate96]

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

[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.

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.

all your videos are beautiful and interesting! Bravo

I ♥ the Alkali Metals

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