Which defect leads to decrease in the density of crystal?
- A F-centre
- B Frenkel
- C Schottky
- D Interstitial
Answer & Solution
Correct Answer
(C) Schottky
Step-by-step Solution
Detailed explanation
In a Schottky defect, an equal number of cations and anions are missing from their lattice sites. This creates vacancies in the crystal structure. Since the number of ions decreases while the volume of the crystal remains effectively constant, the total mass of the crystal…
