Solution

The correct option is B The size of the ions are small
The magnitude of the lattice energy depends as larger the magnitude of the charge of the ions, greater will be the attractive force
smaller the size of the ions, lesser is the inter- nuclear distance and greater will be inter-ionic attraction hence more will be the value of lattice energy

Q. Lattice energy and hydration energy are two important properties of ionic solids on which their melting point, boiling point and solubility depend. Lattice energy increases as the charge on the ion increases and the size decreases. Hydration energy increases as the size of the ion decreases and charges on it increases.
The solubilities of carbonates, sulphates and phosphates of alkaline earth metals are much less than those of the corresponding alkali metals. This is because:

There are 4 ions P, Q, R & S. P has the highest charge and the highest lattice energy among the given ions. What do you think can probably be the size of P?

Q. Based on the ionic crystal lattice above, identify the substance based on the knowledge that the ions are relatively equal in size.

An ion has very high charge and very high lattice energy. What do you think can be the size of this ion?
