WebDiatomic helium molecule (He 2 hypothetical) is the electronic configuration of helium (Z = 2) in the ground state is 1s 2. As each helium atom contains two electrons, there will be four … Weba) He2 -1 b) He2 4+ c) He2 +1 d) He2 2- Obviously b has no electrons and would be bond order 0. Choice c should be bond order 0.5, but I don't understand why choices a and d are not also a bond order greater than 0. Shouldn't the extra electrons go in to a bonding molecular orbital?
