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

electronegativity

solubility of their hydroxides in water

solubility of their sulphate in water

ionisation energy

Text Solution

Verified by Experts

The correct Answer is:

The lattice energy of the hyddroxides of alkaline earth metal decreases more rapidly than their hydration energy leading to more negative value of `Delta H_("sol")` down the group. More negative is `Delta H_("sol")`, more is the solubility of compounds. Hence the solubility of hydroxides of alkaline earth metal increases with their atomic number.

Alkali and alkaline earth metals have low ionisation enthalpies and hence exhibit characteristic flame colouration. They have high negative electrode potentials and hence are strong reducing agents. They dissolve in liquid ammonia to give a solution which conducts electricity and act as strong reducing agent. being stronger reducing agent than hydrogen, they are usually prepared by the electrolysis of their fused chlorides. Their oxides are basic and the basic strength increases down the group. The solubility of carbonates and sulphates of alkali and alkaline earth metals show opposite trends. only the carbonates of Li and alkaline earth metals decompose on heating. The bicarbonates of both alkali and alkaline earth metals on heating give carbonates. Property of alkaline earth metals that increases with their atomic number is
