delta 4d

However, notice that since the 5s atomic orbital is highest in energy to begin with, there is an extra "8.85 eV" ("853.89 kJ/mol") positive difference in energy with respect to the 4d atomic orbitals, so I expect the sigma_(5s) bonding MO to still be higher in energy than either the pi or delta MOs, rather than lower. cinema 4d 2023
