Here is my element collection:



I got my antimony by digesting antimony/tin solder in HCl and utilizing antimony's resistance to acid.
My next editions will be americium, uranium and potassium.
I have isolated many other elements, including bromine, chlorine, and oxygen but my ampoules are to big to fit in the 1"x1 1/2" cells.

Very nice BobD1001 and Pinkhippo11 , I haven't gone back to this thread in a while, so I didn't see those pictures until now....
I will be starting to build my periodic table frame today or tomorrow, hopefully it will be complete within a week or so.
I isolated some more Cadmium (the tiniest amount ever), and I bought a nice light bulb with a really thick Tungsten filament (for a projector.)

You can see the thick W (Tungsten) wire better, if you see the large image, so click it!

Maybe I can get around to posting pics eventually.
Here is a schematic of my actual Elemental State Element collection (except for the bottom row).
Some I have many pounds of, others only a few grams, ALL are at least 99.5% in a few cases, but 99.99++ in the majority. Alfa Aesar, SA etc.

I still have gaps.
If anybody wants to barter or sell to fill these gaps, let me know.

Here's my collection so far. It's very incomplete. I know that the hydrogen should be ampouled, and is probably not going to stay in that vial. That's temporary. The brown vial contains iodine, and the gold colored cylinder contains argon. The element I have which I am most proud of is my indium, which my chemistry teacher gave me. She also had tellurium and antimony but she wouldn't give me those! (not surprisingly) Also, the boron is actually boric oxide as a placeholder until I can obtain the elemental boron from it.

Oh, and this is a close up of some sulfur that I melted down and poured into water, making a ton of little spheres.

Very nice, is that rubber sulfur (melted >300°C) or just melted and poured in water.

When I melted it, I poured some into water to make the balls pictured, and then heated up the remainder to a higher temperature and let it cool to make rubber sulfur. It's really interesting but only stays rubbery for a few minutes before resuming its normal hard form.

From the book Chemical Demonstrations, Volume 1: "After it is removed from the water, the polymeric sulfur will revert to its brittle rhombic form, but the time for the change varies from a few minutes to several hours."
Mine unfortunately only lasted a few minutes.

Now the cooled sulfur is stuck in a test tube, how can I get it out? I can't dissolve sulfur.

I guess you could re-melt it if you're careful.
You could also try using an organic solvent, it's soluble in some.

Hot NaOH dissolves sulphur. Althogh it isn't exactly fast.

I post pictures of chemistry on instagram as bismuthate. http://iconosquare.com/bismuthate

I don't have any solvents that will dissolve sulfur.

Good idea, except hot NaOH also dissolves glass.:o

True but it dissolves sulfur much faster.
I'm not sure but conc. H2O2 may work. Or nitric acid if you'll go to the trouble..

Re-melting…?
Or is it too thinly spread across the test tube for that to be an effective means?

No, remelting it won't help, I'm just cracking and chipping it a way.

Identify the elements.

<a href="http://imgur.com/h2NVOVQ"><img src="http://i.imgur.com/h2NVOVQ.jpg" title="Can you find the hidden nitrogen sample?" width=800 /></a>

Not the biggest collection, but oh well. I have some gallium, but I still can't find it.

From left to right: Au, Cu, ???, Zn?, Ga?, Si, Bi

Zyklonb: Sublime it to the end of the test tube? You'll probably lose some yield to oxides...

You got all of them right except the ??? and Ga. (There is no gallium here)

Au was a graduation gift.
Cu was supposed to go out in the trash but I decided to keep it.
Zn is just a filed down penny.
Si was found somewhere, can't remember where.
Bi was bought at the Smithsonian. It was broken into several small pieces, this is by far the largest.

One of the remaining elements is quite common, the other quite expensive.

I got it out a while ago, acetone and NaOH solution works well for dissolving sulfur. I just didn't know about that at the time.
Brain&Force, gold and bismuth look pretty cool. I haven't spent much time on my element collection in a while, but I really should get some Bi soon.

Having an Element party next month.
