    The structure of ionic compound with Schottky defects has

    A)  same number of cationic and anionic  vacancies

    B)  anionic vacancy and interstitial anion

    C)  cationic vacancies

    D)  cationic vacancies and interstitial cation

    Correct Answer: A

    Solution :

    It is an ionic crystal of the type \[{{A}^{+}}{{B}^{-}},\] equal number of cations and anions are missing from their lattice sites so that the electrical neutrality is maintained, it is called Schottky defect.
