\(\mathrm{NaCl}\) is heated in an atmosphere of sodium vapour. The resultant yellow colour is due to the formation of
- A Frenkel defect
- B Schottky defect
- C F-centers
- D impurity defects
Answer & Solution
Correct Answer
(C) F-centers
Step-by-step Solution
Detailed explanation
Anion vacancies in alkali halides are produced by heating the alkali halide crystals in atomsphere of the alkali metal vapour. When the metal atoms deposit on the surface they diffuse into the crystal and after ionisation the alkali metal ion occupies cationic vacancies, whereas…
