Because arguments based on atomic orbitals focus on the bonds formed between valence electrons on an atom, they are often said to involve a valence-bond theory.. I am sorry, this variant does not approach me. The bond order may be defined as half the difference between the number of electrons in bonding molecular orbitals (Nonbonding) and the number of electrons in the antibonding molecular orbital. The bond order of a He2+ ion is: a. More advanced MO theory shows that σ* is more destabilized with respect to the constituent 1s AOs than the σ is stabilized so the σ(2e⁻) σ*(2e⁻) configuration is at a higher energy (a repulsive interaction) than two separated He atoms. Press J to jump to the feed. Each hydrogen atom contributes one electron, and thus, "H"_2^(-) has three electrons while "H"_2^(+) has one. Is it just that these anions cannot exist at all due to a lack of effective nuclear charge to attract that many electrons?
