Schottky defect is

Options

  1. Avacancy of ions
  2. Bdelocalization of ions
  3. Cinterstitial vacancy of ions
  4. Dvacancy of only cations

Correct answer

A. vacancy of ions

Step-by-step solution

In Schottky defect, some of the lattice points are unoccupied (vacancies or holes). The number of missing cations and anions is the same, thus crystal remains neutral.
