They can behave as a redox reservoir, or they impact the process by changing the basicity of the metal by effective substrate activation. Their utility spans over a number of areas including small molecule activation, homogeneous catalysis, carbon ...7 years ago. We assign oxidation numbers (ONs) to elements using these rules: Rule 1: The ON of an element in its free state is zero — examples are Al, Zn, H₂, O₂, N₂. 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.

The oxidation number method is a way of keeping track of electrons when balancing redox equations. The general idea is that electrons are transferred between charged atoms.
