An Alternative Description for the Electronegativity Difference in Binary Ionic Solids

We are introducing an alternative analytical expression to the electronegativity difference (∆χ) as a function of charge ge, g is factor, fraction electronic devoted bond and e elementary charge, packing factor (p) effective atomic number (Zeff) binary ionic solids, by using very basic Coulomb interaction, modified introduction p, relationship between electric dipole moment (µ) ∆χ in Debye units. When compared Pauling’s, Gordy’s, Allred-Rochow’s Allen’s scales, our calculations deviate around 10% all crystals with such data available literature. A simple satisfactory estimates, no need numerical procedure, announced. The values play important role indicating character chemical bond. It opens up opportunity understand nature bonds able describe bonding any polyatomic system.
