An empirical method is presented for calculating electronegativity of solid metal atom(Z),that is
X=Pexp(-KsR)
where P is Pauling's element electronegativity,1/Ks 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.
