FRENKEL DEFECT: It is a type of defect in crystalline solids wherein an atom is displaced from its lattice position to an interstitial site, creating... WebCorrect options are B) and C) The schottky defect is a vacancy defect (due to missing ions) and also a stoichiometric defect, as the ratio of the number of cations and anions remains the same. (Schottky defects have an effect on the physical properties of solids). It occurs only when there is a small difference in size between cations and anions.
