Which kind of point defect is found in KCl crystal?
Open in App
Solution
The correct option is B Schottky
In ionic crystals, the defect forms when oppositely charged ionsleave their lattice sites, creating vacancies. These vacancies are formed in stoichiometricunits, to maintain an overall neutral charge in the ionic solid. The vacancies are then free to move about as their own entities. Normally these defects will lead to a decrease in the densityof the crystal. It is found in crystals of KCl , NaCl etc.
