Noble gas configurations are stable

In the case of Og, probably not so. Problem is large spin-orbit splitting effects: 7p splits strongly into a more stable 7p_1/2 part and a less stable 7p_3/2 part. Therefore practically the atom rather has four loosely bound electrons significantly above an inert flerovium core, and acts like Sn, which is hardly that noble. At least according to predictions.

I am not sure how to make it correct without jumping into off-topic pedantry, though. Perhaps one could simply say that for the first six noble gases, the general inertness is experimentally known (since Og has not yet been experimentally studied).

The other noble gases are of course not completely inert either, and the reactivity increases gradually with atomic number. At Noble gas#Compounds we do say that "The reactivity follows the order Ne < He < Ar < Kr < Xe < Rn ≪ Og." And at Oganesson#Predicted compounds we mention the large spin-orbit splitting and its expected effects. So here we can link to those articles for more detail. For example, we can just say "Oganesson is predicted to be more reactive". Full stop and the interested reader can follow the link. Dirac66 (talk) 17:43, 26 February 2021 (UTC)[reply]

OK, added a sentence "Oganesson is predicted to be more reactive due to relativistic effects for heavy atoms." Double sharp (talk) 07:10, 14 April 2021 (UTC)[reply]

See article Chemical compound. In Wikipedia it helps to go to the correct article. Dirac66 (talk) 18:09, 23 June 2022 (UTC)[reply]
