The first ionization energy and electron affinity are averaged to obtain the Mulliken scale for it, and the Pauling scale assigns fluorine a value of four.
An equation stating that the square of one measure of this quantity is equal to square of the band gap minus the square of the homopolar band gap was developed by Phillips and van Vechten. The principle of equalization of this quantity states that in a bond, each atom's value for this quantity will be the geometric mean of the atoms' original values; that principle was developed by Sanderson, who computed this quantity as the ratio of atomic number to atomic volume, divided by what would be expected from a linear interpolation of those values for inert gases. The first ionization energy and electron affinity are averaged to obtain the Mulliken scale for it, and the Pauling scale assigns fluorine a value of four. For 10 points, name this measure of an atom's ability to attract electrons to itself.
