Statement-1: In any ionic solid [MX] with Schottky defects, the number of positive and negative ions

Question

Statement-1: In any ionic solid [MX] with Schottky defects, the number of positive and negative ions are same. \ Statement-2: Equal number of cation and anion vacancies are present.

Professor PC Thomas Classes · Answer

In a Schottky defect, an equal number of cations and anions are missing from their regular lattice sites (Statement 2), which strictly maintains the overall electrical neutrality and original stoichiometry of the ionic solid (Statement 1).
