Schottky defect is shown by
Schottky defect is shown by
Show Hint
Schottky defect = equal cation and anion vacancies. It is common when ionic sizes are almost similar.
Updated On: Apr 29, 2026
- Ionic substances in which the size of the cation is smaller than that of the anion
- Ionic substances in which the cation and anion are of almost similar sizes
- Ionic substances in which the size of the cation is larger than that of the anion
- Non-stoichiometric inorganic solids
- Non-ionic substances

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Schottky defect is a vacancy defect found in ionic crystals. Equal number of cations and anions are missing from the lattice to maintain electrical neutrality.
Step 1: Understand Schottky defect.
In Schottky defect: \[ \text{Cation vacancy} + \text{Anion vacancy} \] are formed in equal numbers.
Step 2: Condition for Schottky defect.
It is common in ionic solids where cation and anion have comparable sizes.
Step 3: Choose the correct option.
Hence, Schottky defect is shown by ionic substances having cation and anion of almost similar sizes.
