Explain Schottky and Frenkel defects.

Give three difference between Schottky defect and Frenkel defect.

Which one of the following compound exhibits both Schottky and Frenkel defects ?

Name the ionic solid which shows both Schottky defect and Frenkel defect.

Give example for Schottky defect and Frenkel defect ionic solids?

Due of Frenkel defect

Explain the Schottky defect terms with suitable examples.

NaCl shows Schottky defects and AgCl shows Frenkel defects. Their electrical conductivity is due to the

Calcium crystallizesin fcc unit cell with 0.556 nm . Calculate the density if a. It contains 0.2% Frenkel defects b. It contains 0.1% Schottky defects

Assertion (A) : The density of crystal having Schottky defect is lowered. Reason (R ) : The crystals suffering from Schottky defect have same number of cation and anions missing from their normal lattice sites.
