Out of and , which one shows Frenkel defect and why?
shows Frenkel defect because of the small size of ion, it can easily fit in the interstitial sites while can not as it is bigger in size.

Frenkel defects: It is caused when an ion (cation) leaves its normal site and iccupioccan interstitial position.
It creates a vacancy defect at its original site and an interstitial defect at its new location .
AgCl show Frenkel Defects and NaCl is Schottky Defects.
Because,
• Ionic compounds with low coordination number .
• Anions are larger than Cations . Etc…
Frenkel defect is shown by those in which there is a large difference in the size of cations and anions. ... Hence, the Frenkel defect is shown by AgCl due to the small size of Ag+ ion but not by NaCl because alkali metal ions can not fit into interstitial sites.
