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.
