It is proportional to the reciprocal of the squared covalent radius in the Allred-Rochow scale, though it is more commonly defined as the mean of first ionization energy and electron affinity.
Kabachnik parameters are used in phosphorus chemistry as a generalization of this quantity for groups, and Sanderson proposed a definition for this measure as the reciprocal of atomic radius. It is proportional to the reciprocal of the squared covalent radius in the Allred-Rochow scale, though it is more commonly defined as the mean of first ionization energy and electron affinity. For 10 points, identify this quantity, frequently measured on the Mulliken or Pauling scales, the tendency of an atom to attract electrons in a bond.
