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.

"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.  [[Special:Contributions/172.71.190.132|172.71.190.132]]

"Pentium" was also the first non-numeric name for the Intel family. Before that, it was the 80486/i486. [[Special:Contributions/172.70.134.195|172.70.134.195]] 16:17, 11 January 2023 (UTC)

I have a science textbook at home that doesn't have ''any'' elements in a periodic table, though you'd think it should. It has a very nice ''list'' of elements (with dodgy details, e.g. I think at least one of them was later proven to be two separate but tricky to isolate elements), but was written prior to the popularisation of Mendeleev's table. (i.e. post-1869, but not by much!) Now, obviously, I don't want to diss Randall's humour, but I have so few such retro-geeky things I can brag about so I just wanted to mention this in passing. (Also, when I actually did my own chemistry, the lab wall had a PT on it that featured the element "{{w|Dubnium|Hahniun}}", and some others since replaced/resolved differently. I sometimes still forget myself and refer to the wrong names if I have to answer trivia questions about them ) [[Special:Contributions/172.70.91.127|172.70.91.127]] 23:45, 11 January 2023 (UTC)
