    As semc indicated, the point of learning is to understand the subject, not simply to answer test questions! semc also points you in the right direction. What determines the binding energy of an atomic electron?

    And as GCT indicated, we ask that students submit their work/understanding of the problem and we will then assist. Students are expected to show effort.
