Charges on atoms
[edit]Can we render the charge on the electrons as -1.05? Using -1.1 gives a nonzero sum, and the significant digits rule for additive quantities is to round them to the same power of ten. Olthe3rd1 (talk) 18:22, 12 May 2019 (UTC)
- I changed the writing now, but the original reflected the source. Hoping that balancing is not OR. Actually now I have found the supplementray information has a calculation with more sig figs. Graeme Bartlett (talk) 22:49, 14 May 2019 (UTC)
Name of compound wrong
[edit]The name must be "Disoudium helium", as the compound is an electride. It does not contain He2- ions and therefore is not an helide. Diphosphan (talk) 10:43, 1 July 2025 (UTC)
In addition, the compound is not a salt, it is "expanded" sodium metal, so another point against calling it a helide. — Preceding unsigned comment added by Diphosphan (talk • contribs) 10:45, 1 July 2025 (UTC)
