CHARACTERISTICS OF CRYSTALLINE SOLID


Characteristics of crystalline solid :

 
 
 
 

1) They have a definite and ordering arrangement of the atoms, ions or molecules.

2) They have definite geometrical shape.

3) They consists of large number of tiny crystals called unit cells.

4) Unit cell is repeating structural unit and have definite shape and properties of the crystalline solid.

5) The forces in the crystalline solid may be ionic bonds, covalent bonds, hydrogen bonds or vander

Wall's force .

 6) It has long range order of regular pattern of arrangement which repeats in entire crystal.

7) they have  sharp melting point.

8) Crystalline solids show different physical properties in different directions, hence they are aniso tropic.
