Explanation:
Lithium sodium and potassium all react vigorously with water. Alkali metals need to be stored under oil to prevent them reacting with the oxygen and water vapor in the air. The reactivity of the alkali metals increases down the group. Potassium reacts more vigorously than sodium and lithium is the least reactive.
