When an ion leaves its correct lattice site and occupies interstitial sites in its crystal lattice,it is called
Crystal defect
Frenkel defect
Schottky defect
None
Frenkel defect is generally observed in crystals having lower limiting radius ration
The defect when an ion leaves its lattice point and occupies an interstitial position in the crystal lattice is called ------------------
Schottky defect is observed in crystals when .....................
(a) some cations move from their lattice site to interstitial sites
(b) equal number of cation and anions are missing from the lattice
(c) some lattice sites are occupied by electrons
(d) some impurity is present in the lattice
