REACTIONS OF THE GROUP 1 ELEMENTS WITH WATER " Periodic Table"
All the alkali metals react vigorously with cold water. In each reaction, hydrogen gases given off and the metal hydroxide is produced. The speed and violence of the reaction increases as you go down the group. This shows that the reactivity of the alkali metals increases as you go down Group 1.
