Question:
Identify the type of crystal defect found in \(NaCl\) crystals.
Identify the type of crystal defect found in \(NaCl\) crystals.
Show Hint
Crystals like \(NaCl\), \(KCl\), and \(CsCl\) commonly exhibit Schottky defects due to similar ion sizes.
Updated On: Apr 17, 2026
- Frenkel defect
- Schottky defect
- Metal excess defect
- Interstitial defect
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Crystal defects are imperfections in the arrangement of ions in a crystal lattice.
Two common ionic defects are:
• Schottky defect: Equal number of cations and anions are missing from the lattice.
• Frenkel defect: A cation leaves its lattice site and occupies an interstitial position.
Step 1: Identify the structure of \(NaCl\). \(NaCl\) is an ionic crystal where \(Na^+\) and \(Cl^-\) ions have comparable sizes.
Step 2: Determine the defect type. In such crystals, vacancies of both ions occur to maintain electrical neutrality. This type of defect is called the Schottky defect.
