The correct statement regarding defect in solids is

Options

A. Schottky defect has no effect on the physical properties of solids
B. Frenkel defect is a dislocation defect
C. Frenkel defect is usually favoured by a very small difference in the sizes of cations and anions
D. trapping of proton in the lattice leads to the formation of f- centers.

Answer

B

Explanation

Schottky defect has effect on the physical properties of solids i.e., it decreases the density of crystal. (c) Frenkel defect is usually favoured by a large difference in the sizes of cations and anions. (d) Trapping of electron in the lattice site leads to the formation of F-centers.
