Form $MH_2$ type hydrides with hydrogen on heating.

(B) All the metals of group $2$,except beryllium,when heated with hydrogen form $MH_2$ type hydrides. Hence,statement $(B)$ is correct.Group $2$ elements exhibit an oxidation state of $+2$.Elements at the top of group $2$ do not catch fire when kept on water.The reducing power of group $2$ elements is less than that of group $1$ elements due to higher ionization enthalpy. Hence,statements $(A)$,$(C)$,and $(D)$ are incorrect.
