Question
Which of the following statements are correct in context of point defects in a crystal ?
Options
A.AgCl has anion Frenkel defect and CaF2 has Schottky defects
B.AgCl has cation Frenkel defects and CaF2 has anion Frenkel defects
C.AgCl as well as CaF2 have anion Frenkel defects
D.AgCl as well as CaF2 has Schottky defects
Solution
Since Ag+ (cation) is smaller than Cl- (anion) & hence cation is present in voids.
In CaF2, is smaller.
In CaF2, is smaller.
