Question

In a solid lattice, the cation has left a lattice site and is located at an interstitial position, the lattice defect is (A) Frenkel defect (B) dislocation defect (C) F-centre defect (D) Both(a) and (b)

When an ion (generally cation due to its small size) is missing from its normal position and occupy an interstitial site between the lattice points, the lattice defect obtained is known as Frenkel defect, which is also called dislocation defect.
