Oxidation State

(Oxidation Number)
(number characterizing atoms of a compound as ions)

Oxidation State (or Oxidation Number) is a small integer associated with a compound, indicating the degree of Oxidation of an atom in a compound, i.e., the number of electrons one atom would have "borrowed" from the other, if they were a pair of ions each with filled shells, one positive, the other negative. Such a bond is called an Ionic Bond, but in actuality, bonds are only ionic to a degree, always acting at least in part as if the electrons are shared, i.e., in part, a Covalent Bond.
