Rule 2: The ON of a monatomic ion is the same as its charge — examples are Na⁺ = +1; S²⁻ = -2. Rule 3: The sum of all ONs in a neutral compound is zero.1. Redox. The term "redox" is the combination of two different terms that describe two totally different chemical processes, i.e., "reduction" and "oxidation.". The abbreviation "red" has been taken to distinguish reduction from oxidation that is "ox.". The reduction is a process wherein any chemical entity gets reduced.∆Gº = -nFEºcell. ∆Gº = 2,431,800 J/mol = 2432 kJ/mol (note: Eºcell is negative meaning non spontaneous and ∆Gº is positive, also agreeing with the non spontaneous nature of the reaction)Molecular Redox Reactions.
