What is "Modern chemistry"? Its applications.

Modern chemistry 

In ancient times chemistry was thought a branch of science that discuss about the behaviour of matters and its rule in various transformation from one phase to another.

The modern word chemistry is derived from the arabic word al kimia.

After the dalton's atomic theory and lavoisier's mass Conservation theory Rutherford , niels bohr structure of the atom changed the vision  of chemistry.

Lavoisier accomplished a real revolution that his contemporaries saw as a total break of the past chemistry (alchemy)

It becoming more important to discuss not only about the physical properties like appearance, physical state and smell but also the electronic configuration,electrons in orbitals  sub orbitals, electron cloud around the nuclei, Structures of shell, sub shell, energy absorption, spectra etc.  

Modern chemistry deals with the  composition, structure  Physical and chemical properties of any  natural substance or matter.

Describes about the  transformation of one substance to another substance.

The net energy  changes in reactant and product. 

Net enthalpy chage other terms like 

1.  Gibbs free energy. 

2. Entropy. 

3.  Internal energy. 

4.Reaction rate. 

5. Structure and modification. 

6. Bussiness production of any important compound or substance. 

7. Development of new substances which may be helpful for growth of human civilization.  

Etc. 

 The root of modern chemistry is not lie, instead, medicine, pharmaceutical, natural philosophy ,mineralogy , practices of arts.  

The main aim of modern chemistry is to  easier the process of communication among scientist, Engineer, chemists and related peoples.   

Publishing articles, research paper,  proposals etc are the main dealing     fact of modern chemistry. 

  the development technology  related with chemistry is another applicable path of modern chemistry.
