3. These solids are regarded as true solids.	3. Amorphous solids are regarded as pseudo solids.
4. Crystalline solids undergo regular cleavage.	4. These solids undergo irregular cleavage.
5. These are more rigid.	5. Amorphous solids are not much rigid.
6. Anisotropic in nature i.e. solids in which the properties are different in all directions.	6. Isotropic in nature i.e. Solids in which all the properties are uniform and are independent of direction.
7. Example: Potassium nitrate, copper etc.	7. Example: Cellophane, polyvinyl chloride etc.
