    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

    2. S. Ramanujan

    Srinivasa Ramanujan  (22 December 1887 – 26 April 1920) was famous Indian mathematician. Srinivasa Ramanujan had practically no formal training in pure mathematics but still he made important contributions to mathematical analysis, infinite series, number theory,  and continued fractions.

    3. C.V. Raman

    Sir Chandrasekhara Venkata Raman (7 November 1888 – 21 November 1970) was famous Indian physicist. He won the 1930 Nobel Prize for Physics for his outstanding work in the field of light scattering. He discovered that when light pass through a transparent material, some of the deflected light changes its wavelength. This phenomenon is known as Raman scattering (Raman effect). In 1954, he got India's highest civilian award the Bharat Ratna.

    7. A.P.J. Abdul Kalam

    Avul Pakir Jainulabdeen Abdul Kalam (15 October 1931 – 27 July 2015) was most famous Indian scientist who also served as 11th President of India (2002 to 2007). A. P. J. Abdul Kalam was also known as “Missile Man of India”.  He contribute as a scientist at Indian Space Research Organisation (ISRO) and Defence Research and Development Organisation (DRDO). He was closely involved in India's military missile development efforts & civilian space programme and also contribute in the development of ballistic missile and launch vehicle technology. He also played important role in India's Pokhran nuclear tests in 1974 & 1998. He got India's highest civilian award the Bharat Ratna.

    8. H.G. Khorana  

    Har Gobind Khorana (9 January 1922 – 9 November 2011) was a biochemist. He got the 1968 Nobel Prize for Physiology or Medicine for research that presented the order of nucleotides in nucleic acids. He also received the National Medal of Science in 1987 by the President of the United States.

    9. S.S. Abhyankar  

    Shreeram Shankar Abhyankar (22 July 1930 – 2 November 2012) was famous mathematician. He was known for his great contributions in the field of algebraic geometry, Abhyankar's conjecture of finite group theory.

    10. S. Chandrasekhar 

    Subrahmanyan Chandrasekhar (19 October 1910 – 21 August 1995) was an astrophysicist. He won the 1983 Nobel Prize for Physics for his work on the theoretical studies about structure and evolution of the stars.
