In potassium chloride (KCl), the oxidation number of potassium (K) is +1, and the oxidation number of chlorine (Cl) is -1. This is because potassium, being an alkali metal, typically has an oxidation state of +1, while chlorine, being a halogen, typically has an oxidation state of -1 in its compounds.
