Question

Which stoichiometric defect does not change the density of crystal?

Answer 1

Explanation:

1. Frenkel defect does not change the density of the crystal.
2. It is a type of stoichiometric point defect in which one of the cations gets misplaced from lattice points and is placed in the interstitial site of the crystal.
3. Thus, there is no loss or gain of any ion and so there is no change in its density.
