> Helium is a 'noble element', check the Periodic Table and tell me how Helium gets to be part of a molecule. Unless a lot has changed since I was at school then you aren't going to get a lot of helium 'molecules'. It just doesn't work like that
Yeah, well maybe they don't tell you all the details and special cases in school...
I checked the link and now I see why you didn't post the relevant quote:
"There is some empirical and theoretical evidence for a few metastable helium compounds which may exist at very low temperatures or extreme pressures. The stable cation HeH+ was reported in 1925."
Maybe you do get these things happening inside a particularly pedantic iphone but regular chemistry suffices here, the general idea of the Periodic Table stands true, noble gasses on the right hand side don't react to instantly form co-valent bonds with the other elements. Sure, anything can happen in the side of a giant thermo-nuclear reactor but, in every day situations classical understanding works great.
