... In H2+, the electron doesn’t belong to either atom. In H2+, the electron is in an orbital which spans the molecule – a molecular orbital! Just as atoms have many atomic orbitals (1s, 2s, 2p, etc.), molecules can have many molecular orbitals. In H2+, the higher energy molecular orbitals are all empty ...
