Solids are classified on the basis of the arrangement of their constituent particles.

Crystalline solids:

In a single crystal, the regularity of arrangement of the pattern extends throughout the solid and all points are completely equivalent.

Amorphous solids:

An amorphous solid differs from a crystalline substance in being without any shape of its own and has a completely random particle arrangement, i.e. no regular arrangement. Example: Glass, Plastic.
