Atomic orbitals antibonding molecular

Bonding molecular orbitals increase electron density between the nuclei and are lower in energy than individual atomic orbitals. Antibonding molecular orbitals have a region of zero electron density between the nuclei, and an energy level higher than that of the individual atomic orbitals. 

The labels on MOs indicate their symmetries (shapes), their parent atomic orbitals, and whether they are bonding or antibonding. Antibonding character is indicated by an asterisk. For the H2 molecule both MOs have a symmetry and both are constructed from hydrogen Is atomic orbitals. The molecular orbitals for H2 are therefore labeled as follows ...
