Web21 mei 2024 · Best answer 1. He2+ Helium molecule contains 4 electrons. Out of this 4 electrons, 2 are present in the bonding molecular orbital and the remaining 2 are present in the anti-bonding molecular orbital. Bond order = ½ (Nb -Na) = ½ (2-2) = 0 Hence, He cannot exist. The molecular orbital diagram is given below: He2+ contains 3 electrons. WebHe. 2. The procedure can be introduced by considering the H 2 molecule. Its molecular orbitals are constructed from the valence-shell orbitals of each hydrogen atom, which are the 1 s orbitals of the atoms. Two superpositions of these two orbitals can be formed, one by summing the orbitals and the other by taking their difference.
