In an ionic solid equal number of cations and anions are missing from their regular positions in the crystal lattice creating vacancies is called-

Options

  1. AVacancy defect
  2. BSelf interstitial defect
  3. CSchottky defect
  4. DFrenkel defect

Correct answer

C. Schottky defect

Step-by-step solution

The correct answer is (3) Schottky defect. A Schottky defect occurs in an ionic solid when equal numbers of cations and anions are missing from their regular positions in the crystal lattice, creating vacancies. This defect maintains the overall electrical neutrality of the crystal.
