isotopes. Cerium is highly reactive, and tarnishes easily in the air. It burns readily to form cerium oxide. If you scratch cerium even slightly, it would ignite and burn. Cerium will dissolve in acid. It can oxidize quickly in hot water, and will oxidize slowly in water that is cold, to form cerium hydroxide. It is very active and must be used with caution.
