The defect produced due to the presence of extra cations at interstitial sites is called

Options

  1. Ametal excess defect
  2. BSchottky defect
  3. Cmetal deficiency defect
  4. DFrenkel defect

Correct answer

A. metal excess defect

Step-by-step solution

When a metal contains extra cations (metal ion) in the interstitial site of its lattice. We observe metal excess defect. It is a non-stoichiometric defect.
