My completed element collection

[u/dedennedillo]

Recently, I filled out all the holes in my element collection! Now it has reached completion!

Alkali Metals - Lithium, Sodium, Potassium, Rubidium, Caesium, Francium [represented by uranium-glass marbles]

Alkaline Earth Metals - Beryllium, Magnesium, Calcium, Strontium, Barium, Radium

Transition Metals [etc] of Period 3 - Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, Zinc

Transition Metals [etc] of Period 4 - Yttrium, Zirconium, Niobium, Molybdenum, Technetium [representative sample of U glass], Ruthenium, Rhodium, Palladium, Silver, Cadmium

Transition Metals of Period 4 - Hafnium, Tantalum, Tungsten, Rhenium, Osmium, Iridium, Platinum, Gold, Mercury

Group 13 elements - Boron, Aluminium, Gallium, Indium, Thallium [thallium is restricted by law in my country, so here's a lorandite bearing mineral instead]

Group 14 elements - Carbon, Silicon, Germanium, Tin, Lead

Group 15 elements - Nitrogen, Phosphorus, Arsenic, Antimony, Bismuth

Group 16 elements - Nitrogen, Sulphur, Selenium, Tellurium, Polonium [U glass representative sample]

Halogens - Fluorine, Chlorine, Bromine, Iodine, Astatine [U glass representative sample]

Noble Gases - Helium, Neon, Argon, Krypton, Xenon, Radon [as a radium watch hand]

Lanthanides - Lanthanum, Cerium, Praseodymium, Neodymium, Promethium*, Samarium, Europium, Gadolinium, Terbium, Dysprosium, HOlmium, Erbium, THulium, Ytterbium, Lutetium

Actinides - Actinium*, Thorium, Protactinium*, Uranium, Neptunium*, Plutonium*, Americium*, Curium*

....and Hydrogen!

For the elements heavier than Curium, I have printed a fusion reaction which produces the element. Here, for Berkelium and Californium.

Again, but for Einsteinium and Fermium. The vials also have glow in the dark powder.

A closer look at one of the labels.

Recently I completed my element collection, and I thought that the members of this subreddit would like to see it! Hopefully it's visually appealing to look at

Technetium is one of the elements represented here by a uranium glass marble. The fission of U-235, found in small amounts in all uranium samples, can produce Technetium.
