Vedclass · Answer

(A) Step $1$: $Schottky$ defect is a type of vacancy defect in ionic solids.Step $2$: In this defect, an equal number of cations and anions are missing from their lattice sites to maintain electrical neutrality.Step $3$: Due to the missing ions, the mass of the crystal decreases while the volume remains constant, leading to a decrease in the density of the substance.Step $4$: It is typically found in ionic compounds where the cation and anion sizes are similar. Therefore, option $A$ is correct.
