Which of the following statements correctly differentiates between Schottky and Frenkel defects in a — Solid State Chemistry Question

💡 Solution & Explanation

A Schottky defect is a vacancy defect where an equal number of cations and anions leave the crystal completely, thus lowering the density. A Frenkel defect is an interstitial defect where a smaller ion (usually a cation) moves to an interstitial site within the crystal, keeping the mass and volume (and thus density) strictly constant.
