Late quizzes will receive at least a 10 point deduction. 1. (2 pts) Linus Pauling defined electronegativity, χ , as the “power of an atom in a molecule to attract electrons to itself.” Despite this simple definition there have been many different methods developed for quantifying electronegativity. The Pauling electronegativity scale uses bond dissociation energies to quantify electronegativity (after assigning 4.0 as fluorine’s value). In contrast, the Mulliken electronegativity scale is the average of the ionization energy and the electron affinity (actually, the absolute value of electron affinity) of an element. Briefly explain why it is logical to use electron affinity and ionization energy to calculate electronegativities of the elements. explain why it is logical to use electron affinity and ionization energy to calculate electronegativities of the elements....
