Schottky defect in crystals is observed when

1. an ion leaves its normal site and occupies an interstitial site
2. unequal number of cations and anions are missing from the lattice
3. density of the crystal is increased
4. equal number of cations and anions are missing from the lattice

Correct answer: equal number of cations and anions are missing from the lattice

Solution

Schottky defect occurs when equal numbers of cations and anions are missing from their lattice sites, leading to a decrease in the density of the crystal.
