Add "at STP" to the Boiling-point

Just like is done for the Melting-point. If feels a bit inconsistent now. — Preceding unsigned comment added by Koitus~nlwiki (talk • contribs) 20:52, 15 June 2021 (UTC)[reply]

Other history

Helium was once also produced by fractional distillation of air, and may still be in some parts of the world. In the UK in the post-war period, for example, there were two common varieties of industrial Helium, the expensive US Helium was the purer, while the locally produced variety was from air liquification.

condense hydrogen and oxygen to make rocket fuel

Definitely oxygen can be liquified without liquid helium, usually fractional distillation of liquid air. Hydrogen can be liquified without helium also, but maybe it is easier with helium. Gah4 (talk) 01:19, 11 February 2022 (UTC)[reply]

I suspect ³He. Our article there does mention hypothetical use as an energy source. DMacks (talk) 06:50, 7 October 2022 (UTC)[reply]

Of course. Should have seen that. DePiep (talk) 07:13, 7 October 2022 (UTC)[reply]

There is a ref poking out in the "Conservation advocates" section. That is not how it is done!!! Also. no point having an acrynym if it is not going to ne used.. 103.21.175.235 (talk) 03:31, 31 October 2022 (UTC)[reply]

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]
