Which of the following crystalline compounds are highly prone to exhibiting the Schottky defect, pri — Solid State Chemistry Question

💡 Solution & Explanation

The Schottky defect is favored in ionic compounds where the cation and anion are of almost similar sizes and the coordination number is high. Classic examples include $NaCl$, $KCl$, $CsCl$, and $AgBr$. $ZnS$ exhibits Frenkel defects because $Zn^{2+}$ is much smaller than $S^{2-}$ and the coordination number is low (4:4).
