Question

In a solid lattice, the cation has left a lattice site and is located at an interstitial position. The lattice effect is:

• A. interstitial defect
• B. vacancy defect
• C. frenkel defect
• D. schottky defect

Answer 1

Answer: (A), (C)

The correct options are
A frenkel defect
C interstitial defect

In a solid lattice, the cation has left a lattice site and is located at an interstitial position. The lattice effect is Frenkel defect. This defect is also called Interstitial defect.
In Schottky defect or Vacancy defect, equal number of cations and anions are missing. This maintains electrical neutrality.
