Electronegativity equilibration based on symmetry

A simple rule is deduced, providing new insight into the role of symmetry in determining electronegativity equilibrium. A bell-shaped symmetric graph has been found that interrelates atomic stress and electronegativity in heteronuclear diatomic molecules. This model displays a perspective in which the electronegativity of bonded atoms is equilibrium and the stresses between atoms is equal. The uniqueness of this model is that it can calculate the electronegativity of atoms in different molecules.
