Description for the Electronegativity Difference in Binary Ionic Solids

What is it about?

We are introducing an alternative analytical expression to the electronegativity difference (Δχ) as a function of the charge ge, g is the charge factor, the fraction of the electronic charge devoted to the bond and e the elementary charge, the packing factor (p), and the effective atomic number (Zeff) of binary ionic solids, by using the very basic Coulomb interaction, modified by the introduction of p, and the relationship between the electric dipole moment (μ) and Δχ in Debye units. When compared to the Pauling’s, Gordy’s, Allred-Rochow’s, and Allen’s scales, our calculations deviate around 10% to all ionic crystals with such data available in the literature. A very simple expression with satisfactory estimates, with no need for the numerical procedure, is announced.

Why is it important?

The values of g play an important role in indicating the character of the chemical bond. It opens up an alternative opportunity to understand the nature of ionic chemical bonds and is able to describe the character of the bonding in any ionic polyatomic system.
