Question

State whether true of false :
(a) In Schottky defect, in order to maintain electroneutrality, the number of missing cations and anions are equal.​

Answer 1

Answer:

Explanation:

True

Answer 2

True

Explanation:

An Equal number of cation and anions are missing in Schottky defects.

• The Schottky defect is a vacancy defect (due to missing ions) and also a stoichiometric defect, as the ratio of the number of cations and anions remains the same.
• ( Schottky defects have an effect on the physical properties of solids).

• It occurs only when there is a small difference in size between cations and anions.

Characteristics Of Schottky Defect:

Some distinct characteristics of this defect are;

• There is a very small difference in size between cation and anion.

• Cation and anion both leave the solid crystal.

• Atoms also move out of the crystal permanently.

• Generally, two vacancies are formed.

• As for the density of the solid, it decreases considerably.
