Question:

What is the effect of Frenkel defect on the density of ionic solids?

Options:

The density of the crystal increases.

The density of the crystal decreases.

The density of the crystal remains unchanged

There is no relationship between the density of a crystal and the defect present in it.

Correct Answer:

The density of the crystal remains unchanged

Explanation:

In Frenkel defect, an ion is displaced from its lattice place to an interstitial place. So, there is no loss or gain of ions in lattice structure. It involves only the migration of the ions within the crystal, thus preserving both volume and mass. Therefore, there is no any change in density of the of the crystal.
