Abstract
The relation, where represents the electronegativity of an atom according to Pauling's revised scale, the number of electrons in its incompletely filled (valence) shells, and its single bond covalent radius measured in Angstroms, has been found valid for all elements having values available for comparison, except for Ag, Au, and Cu. This equation is used to extend the electronegativity scale to include a total of fifty-two elements. A chart is constructed to demonstrate the systematic relation of the values to the periodic table. Beginning with the definition of the electronegativity of a neutral atom in a stable molecule as the potential at a distance (covalent radius) from its nucleus which is caused by the nuclear charge effective at that distance, a simple theoretical justification is offered for the existence of a linear relation between and . This relation, like Mulliken's, provides an "absolute" scale of electronegativity values.
