Q.
Alkaline earth metals form hydrated crystalline solids such as $MgCl _{2} \cdot 8 H _{2} O$ and $CaCl _{2} \cdot 6 H _{2} O$. This is due to
The s-Block Elements
Solution:
The hydration energy of the ions of alkaline earth metals $\left(M^{2+}\right)$ is nearly four or five times greater than that of alkali metals because of their small size and increased charge.
