Like Period 1 element, I'm sure this can make GA-standard and I'll work on it. -- Escape Artist Swyer Talk Contributions 23:20, 19 September 2008 (UTC)

The period 2 section is where the IUPAC periodic table begins to go wrong by not stopping at 4 Be Beryllium and starting a period 3 with 5 B Boron, like in the Janet periodic table. Then after the 2 elements of Groups 1 and 2, the third period would still have 8 elements from 5 B Boron to 12 Mg Magnesium. And the subdivisions of the third period would be 2 + 4 = 2 = 8. And the 6 member transition series would be divided into the first 2, and the last 4. See Talk:Charles Janet WFPM ( talk) 21:33, 25 February 2012 (UTC)
There is a move discussion in progress on Talk:Group 3 element which affects this page. Please participate on that page and not in this talk page section. Thank you. — RMCD bot 21:15, 15 January 2013 (UTC)
How can you compare its “inertness” against helium? Which comparison is appropriate? These are the only two elements never forming a covalent bond, except perhaps in some space cations. Incnis Mrsi ( talk) 14:15, 11 August 2019 (UTC)
Guys, you write about things which poorly understand. The reason why a period-2 element can’t “accommodate” more than ten electrons is primarily not orbitals and shells. Every atom, hydrogen included, possesses all n = 1, 2, 3, 4, etc. shells which are available for electrons, possibly in an excited state. The main reason is that for Z ≤ 10 the atom can’t electrically hold more than 10 electrons. Incnis Mrsi ( talk) 14:35, 11 August 2019 (UTC)
