摘要：

All empirical method is presented for calculating electronegativity of solid metal atom (X), that is X = Pexp(-KsR) where P is Pauling's element electronegativity, 1/K-s is the Thomas-Fermi screening lenthg, R is the radius of univalent metal ions. It is found that the X values can give better relationships between X and some thermochemical properties in catalytic process (such as work function, heat of adsorption, etc.) than Pauling's electronegativity.
