The maximum bond order for a diatomic chemical species has been calculated to be six, for example in Cr₂. What types of orbital interactions would be possible in this molecule? Calculate and display the molecular orbitals for Cr₂, and classify them as and as bonding or antibonding. Identify the atomic orbitals used in each molecular orbital. Are your results consistent with a bond order of six? (See G. Frenking, R. Tonner, Nature, 2007, 446, 276 and references cited therein.)
