Yes, I realize some of you don't understand some of that mumbo jumbo (What's a Slater? Covalent? EoV? Is that what you ask?). Well, if it makes you feel any better, I'm clueless with some things myself. One part I don't understand is r/pm E/kJ mol-1. Anyway, the names represent scales, such as the Pauling Scale or Allred scale. For example, n.a. (Pauling) means it's not applicable (n.a.) to the Pauling scale.
