Schottky defect in a crystal is observed when,

Options

  1. AUnequal number of cations and anions are missing from the lattice,
  2. BEqual number of cations and anions are missing from the lattice.
  3. CAn ion leaves its normal site and occupies an interstitial site.
  4. DNo ion is missing from its lattice site

Correct answer

B. Equal number of cations and anions are missing from the lattice.

Step-by-step solution

Schottky deflect arises if equal number of the atoms or ionsare missing from their natural lattice sites and it also decreasethe density of the substance.
