प्रश्न
Frenkel defect does not change the density of the ionic crystal whereas, Schottky defect lowers the density of ionic crystal. Give a reason;
उत्तर
This is because in Frenkel defect no ions are missing from the crystal lattice site whereas, in case of Schottky defect, an equal number of positive and negative ions are missing from the crystal lattice, hence density decreases.
