My collection
Hi, here is my collection of chemical elements, which I am very proud of; it consists of 68 elements, and the lanthanides just arrived today.

Here is my collection as it stands today—68 elements 😆—and I’ve just received all the lanthanides except for promethium and scandium... To think that a year and a half ago, I only had 25 🤯. What do you think of my collection?
Safety question
Hi, I made this post on r/elementcollection, and I wanted to get your opinion on whether my thallium sample is stored correctly. It’s a 1g sample in a glass ampoule embedded in resin, and the whole thing is inside a sealed screw-top vial on my shelf, complete with a label.

Hi, I just spotted this (1g of white phosphorus) on Onyxmet, but I’ve never ordered from them before. Do you have any feedback on this, and how do I buy from their site? Would you recommend this sample?
Hi, I found this pocket watch from the 1910s/1920s for $20, and it registers 0.9 to 1 microsievert on a GC01; I'm wondering if it really is radium?
Hi, I’m looking for tritium and I found this listing from NovaElement—is it any good? Any advice?
Hello, I’m brand new to this community (to be honest, I only discovered you a day ago) and I wanted to get your opinion on a potential purchase: a tritium bulb for my collection, since I’m having trouble finding tritium tubes. This bulb is sold by NovaElement—would you recommend it?
Thanks.
Hi, I just got these items for my birthday—what do you think? And here is my collection of 55 absolutely stunning pieces 🤩; which one is your favorite? I’m curious to hear your thoughts.
Salut, depuis 2–3 mois j’ai un noyau de mangue 🥭 qui pousse, mais au moment où la tige sortait, la racine s’est soulevée du bocal rempli d’eau, a séché et s’est cassée. J’ai pensé qu’il allait mourir, mais non, il a même fait sortir des feuilles. Je me demande quoi faire maintenant ?
Hi, I'm interested in radioactivity detection, which is a really cool hobby, but I don't know which radiocode model to get. I was wondering if you had any advice.
​
PS: I already have a Geiger counter, but it's a cheap, inaccurate model, so I'd like to invest in a proper one.
Thanks
Hi, I was wondering how dangerous this ~12g thallium cube (an incredible sample) is?
Hello fellow collectors, I was wondering what to expect in terms of the appearance of this white phosphorus cube sold by NovaElement?
Here is my thallium, there is about 100mg of it, and I was wondering if it is used in chemistry?
