Property of the alkaline earth metals that increases with their atomic number
A.Solubility of their hydroxides in water✓ Correct
B.Solubility of their sulphates in water
C.Ionization energy
D.Electronegativity
Explanation
Electronegativity as well as ionization energy both usually decrease on moving down in a group with increase in atomic number. The hydroxides and sulphates of alkaline earth metals are ionic solids and the solubility of ionic solids is governed by two factors. Viz, lattice energy and hydration energy. For solubility, hydration energy > lattice energy.
