Question
Assertion: Anion vacancies in alkali halides are produced by heating the alkali halide crystals with alkali metal vapour.
Reason: Electrons trapped in anion vacancies are referred to as F-centers.
Reason: Electrons trapped in anion vacancies are referred to as F-centers.
Answer: Option B
:
B
On heating, the metal atoms deposit on the surface and finally they diffuse into the crystal and after ionization the alkali metal ion occupies cationic vacancy whereas electron occupies anionic vacancy.
