Question

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

• A. The density of the crystal increases.
• B. The density of the crystal decreases.
• C. The density of the crystal remains unchanged.
• D. There is no relationship between density of a crystal and defect present in it.

Answer 1

Answer: (C)

The density of the crystal remains unchanged.

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.

So, option C is the correct answer.
