The correct statement regarding defect in solids is

Options

A. Frenkel defect is usually favoured by a very small difference in the sizes of cations and anions.
B. Frenkel defect is not a dislocation defect
C. Trapping of an electron in the lattice leads to the formation of F-centers.
D. Schottky defect has no effect on the physical properties of solids.

Answer

B

Explanation

Frenkel defect is a dislocation defect because in this defect an atom is displaced from its lattice position to an interstitiaľ site.
