The recent concepts of absolute electronegativity, /chi/, and absolute hardness, /eta/, are briefly reviewed. The operational definitions, /chi/ = (I + A)/2 and /eta/ = (I - A)/2, are used to calculate experimental values for a large number of cations, atoms, radicals, and molecules. The resulting values are shown to be in good agreement with chemical behavior, both as to acid-base character and as to chemical hardness or softness. Anions are modeled by their corresponding radicals, and the importance of local softness, /tilde /sigma//, for delocalized anions is pointed out. Applications of the use of tabulated values of /eta/, both for rank ordering and in numerical calculation, are given. 54 references, 1 figure, 6 tables.
