Question:

Give the significance of a lattice point.

Answer:

In a crystalline solid the constituent particles (atoms, ions) are arranged in a definite and regular order in space and the relative positions of such particles in a crystal are shown by points (.) The arrangement of these points in a crystal is called space lattice. The location of the points in the space lattice are called lattice points or lattice sites. These points are linked by lines to depict the picture of a space lattice. These lattice points arranges in repeated pattern in different directions to form the complete lattice known as the unit cell. These unit cells are of different types and constitutes of different solids.
