UNIT CELL AND SPACE LATTICE

UNIT CELL
Each unit cell must be constituted of atoms, molecules or ions, as the case may be, and arranged to give the particular geometrical configuration of the crystal. The unit cell are of following types:
1. Simple or Primitive Unit Cell (p)
2. Non-Primitive or Multiple Unit Cell

SPACE LATTICE
The position of atoms, molecules or ions in a crystal, relative to one another in space, is usually designed by points such a representation is called Space Lattice.
