WebApr 30, 2015 · The second option is correct: Helium atoms have a filled outer orbital (the s-orbital). There is no place for electron sharing that would have to occur to form He2. The outer orbital of the hydrogen atom is half-filled, which is ideal for electron sharing. This is also the reason why Helium is listed as a noble gas. mascarillas ffp2 beige
