https://en.wikipedia.org/wiki/Big_Bang_nucleosynthesis BBN did only produce unstable Berylium-7 with a half-life of 53.22 days. Thus after 30 minutes there was still plenty of Be-7 left. --172.71.160.38 15:36, 11 January 2023 (UTC)
"unnilium" is a reference to "unnilunium", which was the name for Mendelevium (atomic number 101; from "un nil un", 1-0-1) before it was given a formal name. Therefore the 6th new element referenced, on top of the 4 already in the table, would be #10, or "un nil", or unnilium. 172.71.190.132
