Convert between … WebBased on molecular orbital theory discussed above, the He 2 molecule should not exist since no covalent bond formed between the helium atoms (Equation 9.8.3 ). However, the molecular orbital description above neglects the van der Waals force that exists between the atoms as demonstrated by the existence of liquid helium (at 4 K).

WebSolution. He 2 doesn't exist because helium is a noble gas. They are already stable, they don't lose or gain electrons to become stable. So, He 2 is not possible to exist. 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
