Mulliken Electronegativity

    Mulliken Electronegativity is simply the average of the first ionization energy and electron affinity. Unlike Pauling Electronegativity, Mulliken's equations are absolute and need no starting reference point. (from reference 1)

    xm = (IE1+EA1)/2 (from reference 1)

    Introduction

    Mulliken's background and the significance of this equation. He did all this in 1934! (reference 2)

    The Equation

    Derivation of Mulliken's equation, what each of the terms are, and what this equation gives you

    Why it is significant

    How this equation is better than other predictions of electronegativity, and how this equation is worse.

    Mulliken's equation predicts electronegativity better than just looking at the IE and EA

    Outside Links

    • This is not meant for references used for constructing the module, but as secondary and unvetted information available at other site
    • Link to outside sources. Wikipedia entries should probably be referenced here.

    Problems

    Be careful not to copy from existing textbooks. Originality is rewarded. Make up some practice problems for the future readers. Five original with varying difficulty questions (and answers) are ideal.
