12 Class Chapter 1- Solid State Chemistry

Solid State Chemistry

Solid: - 

        Matter which posses rigidity having definite shape &volume is called solid.

Types of solid:-

1.      Crystalline Solid :- Eg:- Metals And Non metals
2.      Amorphous Solid :- Eg:- Rubber ,Glass ,Plastic

Difference and Comparison between of characteristics

Crystalline Solid: - 

                           Contain regular arrangement having short range & as well as long range order.
Definite geometric shape, Sharpe melting point, they have definite heat fusion, they undergo clean cleavage, and they are true solid.

Amorphous Solid: - 

                         Containing irregular arrangement having short range order only, irregular shape, melting over range of temp, they do not have definite heat of fusion they undergo an irregular cut they are pseudo solid or super cooled solid.

Classification of crystalline solid:-

   1. Ionic Solid 
2. Molecular Solid
3. Covalent of network Solid
4. Metallic Solid

1. Ionic solid: - 

                     In these crystalline solids, constituent particle are positive or negative ion held together by columbic or electrostatic forces of attraction.
Eg:-NaCl, Mgo
