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

"Pentium" was also the first non-numeric name for the Intel family. Before that, it was the 80486/i486. 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 "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 ) 172.70.91.127 23:45, 11 January 2023 (UTC)

It's a proleptic periodic table Sabik (talk)
Indeed, but your comment now makes me wonder what a pre-lepton table would look like. ;) 172.70.85.200 10:00, 12 January 2023 (UTC)

Is there a category for comics about the Periodic Table? I recall one from a year or so ago where the symbols were replaced with ones based on the modern names for the elements. Barmar (talk) 05:29, 12 January 2023 (UTC)

I think you mean 2639, https://www.explainxkcd.com/wiki/index.php/2639:_Periodic_Table_Changes. --172.70.242.156 06:35, 12 January 2023 (UTC)

After an edit, I was left with and adding an -[LINEWRAP HERE]ium" at the end, at least on my display (may depend on browser/display width, etc). If I adjusted the to bring the characters away from the line-wrap point then it could just break again whenever/wherever it found itself back in the same bit of the screen again, so I tried to quote it, but got and adding an "-[LINEWRAP HERE]ium" at the end anyway. If anyone can recall how to implement a 'non-breaking non-space' character, or perhaps wishes to aplly a whole wrap-preventing enclosing tag, then I invite them to apply it there. Assuming it isn't edited out of existence, already, and making the issue moot. ;) 172.70.162.222 16:27, 12 January 2023 (UTC)
