The correct statement(s) regarding defects in solids is (are)A. Frenkel dectes are usually favoured by a very small difference in the size of the cation and anionB. Frenkel defect is dislocation defectC. Trapping of an electron in the lattice leads to the formation of F-centreD. Schottky defects have no effect on the physical properties of solids |
| Answer» Frenkel defect is also called dislocation defect because smaller ions are dislocated from their lattice sites into the interstitial sites. Hence, (b) is correct. Trapping of an electron leads to be formation of F -centre . Hence (c ) is correct. | |
