I'm disappointed that it wasn't scrollable. 2001:41D0:8:5062:0:0:0:1 20:20, 28 January 2026 (UTC)
- +1 And funny to think that the universe contains less than a few hundred mol of Americium. --2001:16B8:CC03:E100:8552:6543:7CF4:9AE7 20:57, 28 January 2026 (UTC)
If anyone's interested in an accessible resource for getting more data like this, may I suggest https://ptable.com/#Properties/Abundance/Universe (which I believe derives data from IUPAC sources) Dextrous Fred (talk) 20:37, 28 January 2026 (UTC) surprised to see so much Astatine, he himself declared, that stuff doesnt want to exist so I expected yet a few powers of ten less
This does make me curious: how would neutronium be represented in a chemical formula? Or would it be? My impression is it kind of exists 'outside' of chemistry... -Kalil 147.81.60.76 21:12, 28 January 2026 (UTC)
- Neutron stars would be represented with n with various mass numbers. And there are no more than 1 mmol (6.02214076×1020) of neutron stars. 2001:4C4E:1C09:EC00:7932:264E:A9E0:8ED0 21:38, 28 January 2026 (UTC)
What about adding mass numbers? For example, most of the hydrogen is 1H, with small amounts of 2H and trace amounts of 3H. 2001:4C4E:1C09:EC00:7932:264E:A9E0:8ED0 21:38, 28 January 2026 (UTC)
