Conclusions
-
1.
The energies of the valence configurations and ionization potentials of atoms and ions of the rare earth elements are estimated from the atomic spectra.
-
2.
Within the framework of the model of valence states according to Van Vleck-Moffitt, the qualitative principles in the geometrical structure, cleavage energies of bonds, and ionization potentials of uni-, di-, and trivalent rare earth elements of the type of MXk m+(k≤3; m=0 and 1) were considered.
-
3.
A nonlinear geometrical structure was predicted for the molecules MX2, MXY, MY2, and MX2 +, and a nonplanar geometrical structure for MX3.
-
4.
On the assumption of additivity of the total bond energies, it was shown that the cleavage energies of the bonds of the molecules MXk m+ should satisfy the additivity rule and that the ionization potentials of the molecules MX, MX2, and MY should be close to the ionization potentials of the central atoms. The correspondence with the mass spectrometric data is satisfactory.
