  1. (i) Schottky defect is shown by the mentioned crystal, as equal number of cations and anions are missing in the crystal lattice.
    (ii) This defect leads to decrease in density, as equal number of the cations and anions are missing from the crystal lattice.
    (iii) This kind of defect is shown by those ionic substance in which the cations and anions are of almost similar sizes.
    Examples : `NaCl, KCl and CsCl`
