Question:
Which of the following statements is correct regarding Frenkel defects?
Which of the following statements is correct regarding Frenkel defects?
Show Hint
A Frenkel defect involves an ion moving from its normal site to an interstitial site.
Updated On: Nov 12, 2026
- It arises due to an equal number of actions and anions are missing from their regular poisons in the crystal lattice.
- It arises when an ion of an ionic compound is missing from its regular site and occupies an interstitial position.
- After the defect density of substance decreases.
- In this, electrical neutrality of the compound is not maintained.
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
A Frenkel defect is also called a dislocation defect.
Step 2: Features
A smaller ion, usually the cation, leaves its regular site and occupies an interstitial position.
Step 3: Consequences
No ion leaves the crystal, so the density is unchanged and electrical neutrality is maintained.
Final Answer:
In a Frenkel defect an ion leaves its site and occupies an interstitial position. \[ \boxed{\text{(B) }\text{It arises when an ion of an ionic compound is missing from its regular site and occupies an interstitial position.}} \]
