Vedclass · Answer

(A) The reactivity of alkaline earth metals with water increases down the group. $Be$ (Beryllium) is the first member of the group and has a very high ionization enthalpy and a small atomic size. Due to its high hydration energy and strong covalent character in its compounds,$Be$ does not react with water or steam even at red heat. In contrast,$Na$,$Ca$,and $K$ are highly reactive and react readily with water to form their respective hydroxides and release $H_2$ gas.

Which of the following metals is inert towards reaction with $H_2O$?
