• Molecular orbital levels Based on hybridisation the occurrence of molecular orbital levels is explained (see Representation of hybridization process). Under absence of energetic excitation (of a energy transfer to the molecule) filling with electrons of molecular energy levels is in increasing order of the energy of the levels (see Diatomic homomolecules of 2nd period). On molecular orbital forming basis and ordered filling of them with electrons the molecular stability are explained. A derived from model of the molecular orbital levels is the bond order. We count as bond order the difference between occupied "bond" orbital levels (lower energy split of the pair of orbital levels) and occupied "anti-bond" orbital levels (upper energy split of the pair of orbital levels). Bond order may take rational values, as in CC from C6H6: 9(bonds)/6(atoms) = 3 / 2.
