Vedclass · Answer

(B) In a crystal lattice,when a smaller ion (usually a cation) leaves its normal lattice site and occupies an interstitial site,it creates a vacancy at its original position and an interstitial defect at its new position. This type of defect is known as the $Frenkel$ defect. It is commonly observed in ionic compounds where there is a large difference in the size of ions,such as $AgCl$,$AgBr$,and $ZnS$.

The defect that arises when smaller cations move into interstitial sites in a crystal lattice is known as ..............
