Vedclass · Answer

(A) Schottky defect is a type of point defect in ionic crystals where an equal number of cations and anions are missing from their lattice sites to maintain electrical neutrality.Since the number of missing cations equals the number of missing anions,the number of vacancies created for both is equal.Therefore,the reason correctly explains why the Schottky defect maintains electrical neutrality by having an equal number of vacancies for both ions.Thus,both assertion and reason are true,and the reason is the correct explanation of the assertion.

Assertion: In an ionic solid $(MX)$,Schottky defect contains an equal number of cations and anions.
Reason: Equal number of vacancies are present for both cations and anions.
