● Explanation -
- Atomic size of alkaline earth metals decreases wrt alkaline metal in corresponding period.
- This decreases hydration energy for formation of crystals in alkaline earth compounds.
- Hence, crystalline salts of alkaline earth metals contain more water of crystallization than the corresponding alkali metal salts.

Verified answer
Alkaline earth metal salts have M2+M2+ ions which has very highpolarising power compared to polarising power of monovalent
metal ion (M+)(M+) of alkali metal Due to high polarising power of
M2+M2+ , it associate more water than M+M+.
