1.	Which of the following statements are correct ?A. The cations occupy more space than atoms in crystal packingB. In Schottky defect, equal number of cation and anion vacancies are presentC. Ionic solids show change in density due to Frenkel defect.D. An increase in pressure on `NaCl` crystal, the `6:6` co`-` ordination changes to `8:8` co`-` ordination
Answer» Correct Answer - a,b,d In Frenkel defect no ions are missing from the crystal as a whole and thus, there is no charge in density
