-A Frenkel defect is a type of point defect in crystalline solids, named after its discoverer Yakov Frenkel. The defect forms when an atom or smaller ion leaves its place in the lattice, creating a vacancy, and becomes an interstitial by lodging in a nearby location.

-Frenkel defects is the defect in which one of the ions leaves its lattice position and moves into an interstitial void, creating a vacancy at the lattice point. Since the ion is dislocated from its lattice site, the Frenkel defect is also known as dislocation defect.
-The effective positive charge of the Cl− vacancy traps the electron released by the Na atom. This trapping of the electrons by anion vacancies results in the formation of F-centers; that is, the electrons released in this process diffuse to the vacant sites where negatively charged ions (i.e., anions) normally reside.

Defects in Solids
Frenkel Defect
- Frenkel defect is a point defect in which an ion is dislocated from its normal lattice site to an interstitial position.
- It is usually favored by a small difference in the sizes of cation and anion.
- This defect does not involve the creation of a new vacancy or an interstitial site.
- Frenkel defects are commonly found in ionic compounds where the cation is much smaller than the anion.
- This defect does not significantly affect the physical properties of solids.
F-Center
- Trapping of an electron in the lattice leads to the formation of an F-center.
- An F-center is an electron trapped at an anion vacancy in a crystal lattice.
- It is responsible for the color of some crystals, as it absorbs light in the visible region of the spectrum.
- The trapped electron can move within the crystal lattice, giving rise to color centers.
Schottky Defect
- Schottky defect is a point defect in which equal numbers of cations and anions are missing from their normal lattice sites.
- This defect leads to the creation of vacancies in the crystal lattice.
- Schottky defects are commonly found in ionic compounds with high coordination numbers.
- These defects do not significantly affect the physical properties of solids.
Correct Statements
Based on the given options, the correct statement(s) regarding defects in solids is (are):
- Frenkel defect is a dislocation defect.
- This statement is correct as the Frenkel defect involves the dislocation of an ion from its normal lattice site to an interstitial position.
- Trapping of an electron in the lattice leads to the formation of F-centre.
- This statement is correct as an F-center is formed when an electron is trapped at an anion vacancy in the crystal lattice.
Therefore, the correct answer is option 'B,C'.
