Which of the following statements for crystals having Schottky defect is not correct?
Schottky defect arises due to the absence of a cation and anion from the position which it is expected to occupy
Schottky defect are more common in ionic compounds with high co-ordination numbers
The density of the crystals having Schottky defect is larger than that of the perfect crystal
The crystal having Schottky defect is electrical neutral as a whole
Due to missing of ions. Density decreases in schottkey defect
