Question

Schottky defect is observed in the crystal of:

• A. $AgCl$
• B. $NaCl$
• C. $MgC{l}_2$
• D. $TiCl$

Answer 1

The correct option is B $NaCl$

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. $AgBr,NaCl$ $\Rightarrow$ Schottky defect abserved in $NaCl$ crystal.
