Jenson's triangle plots chemical species using two values derived from a version of this quantity developed by Martynov and Batsanov.  Sanderson's work on this quanity suggested it should be proportional to the compactness of the atom, explaining why it decreases down a period.  One measure for this quantity comes from bond energy, while another is simply the average of the electron (*) affinity and ionization energy; those are named for Pauling and Mulliken.

One measure for this quantity comes from bond energy, while another is simply the average of the electron (*) affinity and ionization energy; those are named for Pauling and Mulliken.   Flourine has the highest value of, for 10 points, what quantity that predicts polar bonds by measures the tendency of a nucleus to attract electrons?
