Question:

Schottky defect in crystals is observed when:

equal number of cations and anions are missing from the lattice

density of the crystal is increased

an ion leaves its normal site and occupies an interstitial site

unequal number of cations and anions are missing from the lattice

Solution:

Schottky defect is observed when equal number of cations and anions are missing from the lattice. This defect changes the density as a pair of ions are missing from the lattice.
