Question
Write the consequences of Schottky defect with reasons.

Answer

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