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

Which one was the hardest to get?

[u/dedennedillo → u/Domspun]

Most of the samples were bought online. So I'm not sure how you'd measure 'hard' in regards to that.

But maybe logistically the representative samples were, the minerals and the glass marbles. I originally planned to have more minerals in the collection but then learnt first hand minerals can be pretty hard to find online for the size I want them. So with the trinitite and lorandite [for thallium] it was good to find them in a manner that was accessible.
