1) Assertion (A): The diagram shows Schottky defect.
Reason (R): Schottky defect occurs in ionic solids.
2) Assertion (A): LiCl Crystal is pink.
Reason (R): Pink colour of LiCl crystal is due to excess Lithium.
3) Assertion (A): The crystal lattice density increases due to the
defect shown in the diagram.
Reason (R): Tetrahedral voids are surrounded by 4 constituent
particles.
