WebHelium is het enige element dat bij normale druk niet in een vaste stof overgaat beneden een bepaalde temperatuur. 4 He kan alleen onder hoge druk (minimaal 2,6 M Pa) vast … Helium has the highest ionisation energy, so a He ion will strip electrons off any other neutral atom or molecule. However it can also then bind to the ion produced. The He ion can be studied in gas, or in liquid helium. Its chemistry is not completely trivial. For example, He can react with SF6 to yield SF 6 or SF 5 and atomic fluorine. He 2 was predicted to exist by Linus Pauling in 1933.
