In a solid lattice the cation has left a lattice sirte and is located at an interstital position , the lattice defect is

Options

A. Frenkel defect
B. Schottky defect
C. F-centre defect
D. Valency defect

Explanation

When an ion (generally cation due to is small size) is missing from its normal position and occupy an interstitial site between the lattice points, the lattice defect obtained is known as Frenkel defect.
