Pauling first proposed the concept of electronegativity in 1932 to explain why the covalent bond between two different atoms (A–B) is stronger than the average of the A–A and the B–B bonds. According to valence bond theory, of which Pauling was a notable proponent, this "additional stabilization" of the heteronuclear bond is due to the contribution of ionic canonical forms to the bonding. WebFeb 28, 2024 · However, Pauling was the first scientist to propose a measurable scale for electronegativity and to fully define the concept as we know it today.
