Property of the alkaline earth metals that increase with their atomic number (AIPMT 2010)
A.electronegativity
B.solubility of their hydroxides in water✓ Correct
C.solubility of their sulphates in water
D.ionisation energy
Explanation
Solubility of alkaline earth metals hydroxides in water increases with the atomic number. It is due to the decrease in lattice energy more than the hydration energy. Whereas solubility of alkaline earth metal sulphates in water, electronegativity, and ionization energy decreases down the group.
