Abstract

Abstract: In order to investigate the intrinsic relationship between the physicochemical property and the structure ofinorganic materialsa new topological indexmZ of the valence electron orbit energy was proposed．This index was con-structed by the formation of point valence value which consisted of the valence electron orbit energy E i of the atom and the outermost effective main quantum number of atom n ∗i ．The corresponding0-and1-rank indexes of m Z were then respectively fitted with the pKa 1 values of inorganic hydridesthe lattice energy Uformation enthalpyΔ f Hθm and hy-drated energyΔ f Gθm of20kinds of alkali halidesand the internuclear distance R 0 of the gaseous alkali halidesThe re-lated coefficients（re-related coefficients） of the corresponding regression equations are respectively0．9962（0．9966）0．9966（0．9981）0．9769（0．9830）0．9768（0．9798） and0．9963（0．9963）the obtained results being better than those reported in the former literatures.

Key words: valence electron orbit energyconnection index, correlativity, inorganic hydride, lattice energy, forma-tion enthalpy, ion-ydrated energy
