1.	In a crystal, some ions are missing from normal sites. This is an example of `:`A. `F-` centresB. interstitial defectC. Frenkel defectD. Schottky defect
Answer» Correct Answer - d Schottky defects are arised when one positive ion and one negative ion are missing from their respective positions leaving behind a pair of holes. These are more common in ionic compounds with high co`-` ordination number and having almost similar size of cations and anions.
