What does your periodic table look like? (collection)
Finaly, my periodic table callection is almost comlepte! But I have som questions...
Should I buy the gases?
It's not fun to buy "empty" ampoulles with the gases, like this; https://www.ebay.com/itm/232698640768 and then chlorine and fluorine https://www.ebay.com/itm/264779471972 on that. It's expensive and invisible! Yes I know, I should buy them for the best collection... How do you
do to repressent your gases? Do you have them? How can I trust that it's the real gases, with electrical discharge?
Then, of course, over number 92, U, its impossible (except the 0,26 µg Am from a smokedetector). But I would have a little piece of Th and U, I dont
think its impossible...
And, I think I put som uranium-ore in the jars for repressent Po, At, Rn, Fr, Ra*, Ac and Pa. Or howe do you think about that? There is at least some
atoms of it in the ore...
*Well, I had Ra in clockfinger, but it wasn't legal and I was convicted. But to small pieces of U and Th doesn't reach up to 100 kBq.
Well, that was what the witness from the Swedish Radiation Safety Authority said in the court was legal to own, and have in your home...!? But I think
he just invented it...
And at least, what should I have to repressent Tc and Pm? I have worked with Tc, I practiced at the hospital in the nuclear physics department, but I
can't go in there anymore... The know now that I stoled things from the department! But it's 24 years ago I was there...
And I already have two gases, and the air is mostly nitrogen...

I think gas discharge tubes are probably best for most of the gases.
Liquid Cl2 is possible. Or dissolved in something like CCl4. IIRC, woelen has samples like that.
I have a piece of antozonite for fluorine.
I have resolved to be content with representations for the radioactives. I don't think there are many options there. A medical label of something
related to Tc would be great, but J have no idea how I might obtain something like that.

For the gases, I have both a small sealed bottle (which fits physically with my set, though I don't trust them too much), and gas discharge tubes
(very small amount, but I can trust these!). I have some liquid Cl2 (in a vial encased in resin), and would like some liquid Xe some day (very
expensive). I also have a piece of antozonite for F2.
For the radioactives, a piece of natural U ore covers a lot of them, and for At/Tc/Fr I do not know of any other way to get any atoms. With your smoke
detector source of Am-241, do not forget that each alpha decay gives you a new atom of Np-237, most of which you will keep forever. I have also
sourced a piece of trinitite for Pu, and anti-static brushes for Po. In the past, camping lantern mantles used some Th, I have some of these old
mantles, and decays also create some Pa.

I have neon indicator lamps for neon. There are pea sized discharge lamps that can be had for a few dollars and larger neon indicator lamps like the
GE NE34 if you want a larger sample. The lamps are powered by 120/220V AC. For xenon I have a flash tube that is meant for a camera.

If you are rich, you can buy Tc sample from Oxymet for 415 €.
https://onyxmet.com/index.php?route=product/product&path...
It is gold foil covered with layer of 99-Tc.

GOLD as substrate?! Why not something cheaper like copper?!

Gold foil is cheap, it is really not much. I don't know how they put the Tc on, but I guess gold foil is cheaper than anything else.
The foil is so cheap they put it in gold strike liquor as a decorative, there are milligrams in a bottle.

Probably by electrolysis of pertechnate solution, I read something about that few days ago.

Gaseous chlorine samples are interesting. You can clearly see the pale green color of the gas. I indeed have samples of Cl2, dissolved in CCl4 until
saturation, which I made myself. Of the noble gases, oxygen, nitrogen, hydrogen and deuterium I have glass ampoules with the low pressure gas, which
can be excited with a high frequency high voltage source.
I leave out strongly radioactive elements, indicating that they do not occur naturally on earth, except maybe in trace amounts in a transient state,
as decomposition products of uranium and thorium. I have an old sample of oxidized thorium metal in a glass ampoule, and unfortunately I still do not
have an uranium metal sample. That is the last element which I have to add to my collection.

I've got small samples of every element up to Bismuth (83) except the two unstable ones. Tc and Pm. I haven't bothered with any radioactives and the
fluorine is as a sample of fluorite. Most were bought, but some (Bromine, Iodine and Chlorine were prepared myself). I am happy that I got a decent
sample of Palladium (1.2g) before the price skyrocketed and some decent samples of the Lanthanides. I have them all presented in a Periodic table
display on the wall. I'll post some snaps later.
If you're not part of the solution, you're part of the precipitate.

THat's pretty nice, Xanax. Good effort.
What's the stain by the tellurium?

First I hade the iodine in an ampoule which was placed where the tellurium is now. Even it was a sealed ampoule, the fumes passed thru. Maybe white
was a bad choise for the shelf, because then I just took a smaller sample of iodine in a platsic jar, so it becomes even more fumes...

The ampoule must have not been fully sealed. I have some iodine that’s been ampouled for years with no leakage whatsoever. You could probably wash
the shelf with some bisulfite solution (or if that doesn’t work, just repaint it) and put a new, better ampoule in its place.

The largest periodic table I have right now is on the cover of my element collection...
more pics here
I hope to get a big one that I can put up in my lab.... whenever I get a house that has a garage that I can turn into a lab, lol.
P.S. If anyone wants specific pictures of any of the elements in my above collection, just let me know.

can you post a picture of natrium? and neodymium?
I am short on samples, but they will come gradually.

Sure! Here are some pics
 
I love the chunks of sodium I have as a sample, because you can actually see the purity with the crystalline structure. Absolutely gorgeous.
Then I couldn't resist the chance to show off my other Alkali metals :-D
Even though you don't have many samples yet, I'm envious of your display and setup. It's gorgeous! You obviously understand that presentation is
important :-) I look forward to seeing your collection grow in size in the future.

CouchHatter - hopefully carbon, iron and lead come quickly for you 
Xanax - that's a nice chunk of rhenium you have there, that stuff is around $5/gram!

I got a new new elemental silver "samples". Posting them here on the off-chance someone else might find them as neat as I do.
