Question

Property of the alkaline earth metals that increases with their atomic number:

• A. Solubility of their hydroxides in water
• B. Solubility of their sulphates in water
• C. Ionization energy
• D. Electronegativity

Answer 1

The correct option is A

Solubility of their hydroxides in water

As we go down the group – the solubility of the alkaline earth metal hydroxides increases. The solubility of alkaline earth metal sulphates decreases as we go down the group. Both ionization energy and electronegativity decreases as we go down the group.
