Question

(A) In $Schottky$ defect,equal numbers of cations and anions are missing from their lattice sites,which leads to a decrease in the mass of the crystal

Vedclass · Accepted Answer

Density decreases in Schottky defect and remains unchanged in Frenkel defect.

Vedclass · Answer

(A) In $Schottky$ defect,equal numbers of cations and anions are missing from their lattice sites,which leads to a decrease in the mass of the crystal while the volume remains constant. Thus,the density of the crystal decreases. In $Frenkel$ defect,ions (usually cations) leave their lattice sites and occupy interstitial sites. Since no ions leave the crystal,the mass and volume remain unchanged. Thus,the density of the crystal remains unchanged.
