The correct statement among the following, regarding defects in solids is
) Frenkel defect is favored by small difference in the sizes of cation and anion.
) Frenkel defect is a metal excess defect.
) Trapping of electron in the lattice leads to formation of F-centres.
) Schottky defect has no effect on the physical property of solids.
) Frenkel defect is favored by small difference in the sizes of cation and anion.
) Frenkel defect is a metal excess defect.
) Trapping of electron in the lattice leads to formation of F-centres.
) Schottky defect has no effect on the physical property of solids.
- A
- B
- Correct answerC
- D
Solution
The re-written correct statements are:
) Frenkel defect is favored by large difference in the sizes of cation and anion.
) Frenkel defect is a dislocation defect.
) Trapping of electron in the lattice leads to formation of F-centres.
) Schottky defect has effect on the physical property of solids like density, etc.
Hence, the correct answer is option: 'C'.
