The correct statement(s) regarding defects in solids is / are
Frenkel defect is a dislocation defect
trapping of an electron in the lattice leads to the formation of F-center
⇒ Schottky Defect → Equal number of anions and cations are missing
No. of ions decreases, volume remains same ⇒ Density decreases.
⇒ Frenkel Defect → If an ion is missing from lattice site and occupying interstitial site
Favoured in compounds : favoured in compounds in which there is large difference in size of cations and anions. with low coordination no.
⇒ F- centres ⇒ Sites where anions are missing and instead electrons are present
