System of metal electronegativities calculated from the force constants of the bonds

It is proposed to use a unified one-parameter equation which relates the force constants in molecules and crystals to the electronegativities of atoms. The results obtained for all currently studied compounds depend little on the ligand type, which made it possible to construct a complete electronegativity scale for elements in molecular and crystalline states equivalent in known cases to the thermochemical Pauling scale. An attention is paid to the chemical bond characteristics in some molecules and crystals of b subgroups.
