Statement 1: Frenkel defects are shown by silver halides.Statement 2: Ag+ ions have small size.

In frenkel defect also called dislocation defect the smaller cation is dislocated from its normal site to an interstitial site.Frenkel defect is shown by ionic solids in which  there is large difference in the size of ions.It is observed in ionic crystals of low co-ordination  number (4 or 6)
