1.	When electrons are trapped into the crystalline anion vacancy the defect is known asA. schottky defectB. Stoichiometric defectC. Frenkel defectD. F-centres
Answer» Correct Answer - 4 The lattice sites containing the electrons trapped in the anion vacancies are called `F-`centres because they are responsible for imparting colour to the crystals (`F=`Farbe which is a German word for colour).
