Which is the incorrect statement. – InterviewSolution

1.	Which is the incorrect statement.
Answer» Density decreases in case of crystals with Schottky's DEFECT NaCl[s] is insulator, silicon is semiconductor , sivler is CONDUCTOR, quartz is piezo electric crystal. Frenkel defect is favoured in those ionic COMPOUNDS in which sizes of CATION and anions are almost equal. `FeO_(0.98)` has non stoichiometric metal deficiency defect. Solution :In Frenkel defect the radius of cation MUST be very less than anion.
