Question

How does frenkel defect is affect density of the solid?

Answer 1

A Frenkel defect or dislocation defect is a type of defect in crystalline solids where in an atom is displaced from its lattice position to an interstitial site, creating a vacancy at the original site and an interstitial defect at the new location without any changes in chemical properties.[1] This defect appears in ionic solids, and the smaller ion (usually cation) is dislocated. Frenkel defects are often shown by ionic substances with a large difference in the size of ions; e.x. they appear in ZnS, AgCl, AgBr, and AgI due to the small size of the zinc ion with charge +2 and the silver ion with charge +1.

Answer 2

HEY MATE HERE IS YOUR ANSWER:-

This defect is shown by ionic solid this defect was pointed out by Frankel a Russian scientist in the 1926 in this defect an ion is missing from its normal position and occupies an interstitial site between the lattice points.eg are AgBr, AgCl.
