#crystallattice • #unitcell • • A crystal is made up of atoms, ions or molecules. In crystalline solids, these atoms, ions or • molecules are located at deinite positions in space. • These positions are represented by points in a crystal. • These points are called as lattice points or lattice sites. • This arrangement of points in a crystal is called crystal • lattice or space lattice. • So a crystal lattice is an array of points representing • atoms, ions or molecules of a crystal, arranged at • diferent sites in three dimensional space.
