Covalent radius

How does the concept of covalent radius make sense for helium, as it doesn't normally bond with anything? If it is based on a measurement of a bond in some actual helium compound, what is the compound? It seems like a reference is needed in the infobox.CountMacula (talk) 15:59, 8 November 2022 (UTC)[reply]

Hmm. In Covalent radius it says: Tabulated values of covalent radii are either average or idealized values, which nevertheless show a certain transferability between different situations, which makes them useful. I suspect the idealized values part allows it. Note that on Covalent radius it has two (very) different values for helium. I suspect that not putting one on this page would be a good choice. Gah4 (talk) 18:30, 8 November 2022 (UTC)[reply]

There are known bound ions containing helium, see Helium compounds#Known ions. I don't think it's too much of a stretch to consider HeH⁺ to contain a H–He covalent bond, so these values make sense even without idealisation. The bigger problem to my mind is that the two values are very different, as Gah4 says. Double sharp (talk) 17:00, 29 December 2023 (UTC)[reply]

Where they say that large amounts of helium-4 are made in stars, add to it "and a little more from alpha decaying radioactive materials" or some variation thereof. RealNamesAreFineZ.E.O (talk) 17:06, 6 September 2023 (UTC)[reply]
