For 10 points, name this number that represents the number of electrons an atom gains or loses when forming a chemical bond, which is useful when balancing redox reactions.
Stock nomenclature is used to designate this value for the central atom of a complex. Latimer and Frost-Ebsworth diagrams represent the potential difference between atoms with different values of this number. Due to the presence of an oxygen-oxygen bond, this value is (*) negative one for oxygen in hydrogen peroxide. When this number decreases for a species, reduction has occurred.
