Earth has retained all of the noble gases that were present at its formation except helium.[edit]

According to the helium article there is more helium in the atmosphere than krypton. Why the inconsistency? Gjxj (talk) 21:20, 11 December 2020 (UTC)Reply[reply]

That's not a mistake. The helium in the atmosphere is not the helium that was present at the Earth's formation, but is pretty much all produced by radioactive decay. Get a uranium-bearing rock, the U shoots out alphas, those grab electrons and become helium atoms. Over a long time scale they eventually diffuse out and into the atmosphere because He atoms are so small. Although once it's there we again start losing it because it's too light to hold on to, so we basically just have an equilibrium amount. We have enough U and Th in the earth that the He produced this way that leaks into the atmosphere is enough to be more than the small amounts of Kr and Xe we have. But we have more Ne and Ar than He.

Error in the Chemistry section[edit]

Hello,

As I cannot edit this article myself, I decided to make a note of an error I noticed. In the Chemistry section, there is a reaction formula which goes as follows: 2KFr -> 2Kr + F2 Now on the left we see some Potassium Francium compound, which should be 2KrF, a Krypton Fluorine compound. — Preceding unsigned comment added by TheFrunk (talk • contribs) 21:00, 14 March 2022 (UTC)Reply[reply]

Good catch, fixed it. ComplexRational (talk) 01:29, 15 March 2022 (UTC)Reply[reply]
