Explanation:
Redox reactions are defined as the reactions where one element is oxidized (so the oxidation state is increased); and another element is reduced (oxidation state decreases). These changes in the oxidations states are defined by a transference of electrons.
When the oxidation state decrease → reduction → the element gains electrons
When the oxidation state increase → oxidation → the element release electrons
