Schottky defect is observed in crystals when………… .

Answer»

some cations MOVE from their lattice site to interstitial sites. 
equal number of cations and anions are missing from the lattice. 
some lattice sites are occupied by electrons. 
some impurity is PRESENT in the lattice. 

SOLUTION :The ionic CRYSTALS with nearly same sized cations and anions show Schottky defects where equal number of cations and anions are missing from lattice site to maintain ELECTRICAL neutrality.
