Assertion:Frenkel defect is also called dislocation defect Reason:Frenkel defect is shown by ionic substances in which cation and anion are of almost similar sizes.
(A) KCL is more likely to show Schottky defect ,while Li is more likely to show Frenkel defect. (R) Schottly defect is found in those ionic solid which have cation and anion of similar size while Frenkel defect is more likely found in those solids which have cation of smaller size.
A : In Schottky defect, density of crystal decreases. R : Equal number of cations and anions are missing in Schottky defect.
Ionic lattic has two major points defects ,(1) Schottky (2) Frenkel defects . Schottkly defects occurs due to the cations - anion pair's missing from the lattice sites . Frenkel defects occurs levels its lattic site and fits into an intersitial space. The neturaity of the crystal is benig maintained and we considerd all losses from interstitical positions. which defect decrease density of the crystal ?
