The correct statement(s) regarding defects in solid is (are) — Solid State Chemistry Question

💡 Solution & Explanation

Frenkel defects occur when there is a large difference in size between cations and anions (the small cation is dislocated to an interstitial site). Trapping of electrons in anion vacancies forms F-centres, which give colour and paramagnetism. Schottky defects decrease density and lattice energy.
