Question

which of the following is correct? (1) Schottky defect lowers the density of crystal Frenkel defect increases the dielectric constant of crystals Stoichiometric defects make crystals good conductors of electricity All the three are correct​

Answer 1

Answer:

Correct option is

D

All the the above

Schottky defect arises due to a vacancy at an anion site which of course is accompanied by a vacancy at a cationic site to maintain the electrical neutrality of the system. As a result of the Schottky defect, the density of the crystal decreases as there are a lesser number of ions. Frenkel defect increases the dielectric constant of the crystals due to the closeness of the like charges. Stoichiometric defects make the crystals good electrical conductors. The crystals conduct electricity to a small extent by an ionic mechanism.

Hence, all the three statements are correct
