Which one below is not true for Frenkel and Schottky defects in ionic solids? * . (4 Puan) O Frenkel defect involves a cation-vacancy and a cation-interstitial pair. When Frenkel defect occurs, there is no change in charge because the cation maintains the same positive charge as an interstitial. When Schottky defect occurs, the charge neutrality of the crystal is not maintained because it involves both anions and cations. O Schottky defect involves a cation vacancy and an anion vacancy pair.
