(a) some cations move from their lattice site to interstitial sites

The defect when an ion leaves its lattice point and occupies an interstitial position in the crystal lattice is called ------------------

Ionic lattice has two major points defects, (1) Schottky (2) Frenkel defects. Schottky defects occur due to the cation-anion pair's missing from the lattice sites. Frenkel defects occur when an ion leaves its lattice site and fits into interstitial space. The neutrality of the crystal is being maintained and we considered all losses from interstitial positions.

The structure is shown here represents :
