Question
Write the consequences of Schottky defect with reasons.
Solution
Consequences of Schottky defect are:
- As the number of ions decreases, mass decreases. However, volume remains unchanged. Hence, the density of a substance decreases.
- The number of missing cations and anions is equal, and the electrical neutrality of the compound is preserved.
- This defect is found in ionic crystals such as NaCl, AgBr and KCl.
