$\large{\red{\underline{\tt{Answer}}}}$

Calcium, strontium and barium

Calcium, strontium and bariumThese all react with cold water with increasing vigour to give the metal hydroxide and hydrogen. Strontium and barium have reactivities similar to lithium in Group 1 of the Periodic Table. Calcium, for example, reacts fairly vigorously with cold water in an exothermic reaction.

Answer 2
