MCQ
Schottky defect is observed in the crystal of:
- A$\text{AgCl}$
- ✓$\text{NaCl}$
- C$\text{MgCl}_2$
- D$\text{TiCl}$
✓
Answer
Correct option: B.
$\text{NaCl}$
Schottky defect is a type of point defect in crystal lattice named after walter $H$ scottky. In non$-$iodic crystals, it means a lattice vacany defect. In ionic$-$crystals, the defect forms when oppositely charged ions leave their lattice sites, creating vacancies.
Eg$. \text{AgBr, NaCl}.$
$\Rightarrow$ Schottky defect abserved in $\text{NaCl}$ crystal.
Eg$. \text{AgBr, NaCl}.$
$\Rightarrow$ Schottky defect abserved in $\text{NaCl}$ crystal.
