Which of the following solid ionic compounds is well-known for exhibiting both Schottky and Frenkel — Solid State Chemistry Question

💡 Solution & Explanation

$AgBr$ is a unique ionic solid that exhibits both Schottky defects (due to similar sizes of $Ag^+$ and $Br^-$ enabling both to leave the lattice) and Frenkel defects (due to the high mobility and relatively small size of $Ag^+$ allowing it to occupy interstitial sites).
