A species whose oxidation number increases in a reaction is oxidized (reducing reagents or reactant).

For example, balanced chemical reaction: 2KClO₃ → 2KCl + 3O₂.

Oxygen in the reactant state has oxidation number - 2 (+1 + 5 + 3 · x = 0) and it is oxidized to 0 (in molecule of oxygen) in the product state.
