This edit request has been answered. Set the |answered= or |ans= parameter to no to reactivate your request.
The heading "Heat of vaporisation" is spelled "Heat of vaporization" on other Chemical Element Wikipedia entries, for example "Barium", and should be altered accordingly.
This heading appears in the data column on the right of the main text. 120.149.83.176 (talk) 06:37, 11 January 2023 (UTC)Reply

Why would simple units conversion require citation? Aluminium's density is 2700 kg/m3 and its conductivity 37.7 MS/m (26.5 nΩ⋅m); for Calcium that's 1550 kg/m3 and 29.8 MS/m (33.6 nΩ⋅m) respectively. Conductivity by mass is therefore 14 kS/kg/m2 for Aluminium and 19.2 kS/kg/m2 for Calcium. For completeness sake, Copper figures are 8960 kg/m3, 59.6 MS/m (16.78 nΩ⋅m), 6.6 kS/kg/m2 (poor conductivity for a given weight of cable). 188.120.48.205 (talk) 20:32, 23 November 2023 (UTC)Reply
Thanks Fullmetalgrudo, I find other recent authoritative sources agree with your post and updated the article to state that it changes from fcc to bcc as you note. The source I used (Arblaster 2018) says that publications from 1956 and 1958 "reported an intermediate hexagonal close-packed (hP2) structure but Peterson and Fattore 1961 showed that this was due to hydrogen contamination." –MadeOfAtoms (talk) 10:08, 20 April 2024 (UTC)Reply

One application I had read about elsewhere in Wikipedia which I didn't see on this page is that calcium can be alloyed with magnesium to prevent it from catching fire; while alloying aluminum with magnesium also reduces the risk of catching fire, such alloys can still catch fire at very high temperatures, while a suitable alloy with calcium would not catch fire under any circumstances.

level-4 vital article is rated GA-class on Wikipedia's content assessment scale.
Not done That is because this article is written in en-GB not en-US. For more background, see WP:ENGVAR. -DePiep (talk) 08:25, 11 January 2023 (UTC)
