How did Pauling define electronegativity?

Answer 1

Pauling's definition of electronegativity

Electronegativity is defined as the attracted force which an atom, bonded by a covalent bond, exerts on the bonded pair of electron responsible for the covalent bonding.

Answer 2

Pauling defined electronegativity as the ability of an atom to attract electrons towards itself in a chemical bond. He developed a scale to quantify electronegativity values for elements based on their chemical properties. A higher electronegativity value indicates a greater ability of an atom to attract electrons in a bond.
