  1. 1.

    The available experimental material on the energies of atomization of simple inorganic and heteroorganic molecules of nontransition elements of the type of MXk, MXi′Xk-i, MXi′Xj″Xk-i-j‴, etc. is generalized.

  2. 2.

    From the nature of the changes in the average energy of the M-X bond in various theories (along the periods, along the groups, with changes in the valence of the central atoms M, with ionization, in isoelectronic series, etc.), the entire aggregate of ligands X is broken down into two groups (σ and σ + π), in accord with whether or not the atom A in the ligand directly bonded to the central atom M possesses unshared pπ-electron pairs.

  3. 3.

    The basic principles of the behavior of the average bond energies in the enumerated series, their differences and similarity, were followed.
