Abstract

The oxidation state of an element is a practically useful concept in chemistry. IUPAC defines it as “the charge an atom might be imagined to have when electrons are counted according to an agreed-upon set of rules”.(1) Once the composition of a compound is known, a trained chemist will immediately infer the oxidation states of its components, and in turn anticipate the structural, electronic, optical and magnetic properties of the material. This is a powerful heuristic tool.
