Chemistry is very important science as it includes a lot of fields. Chemistry sciences deal with the study of the natural elements and compounds that compose both living and non-living materials on the planet. Chemistry is primarily concerned with the relationship that binds these elements and compounds in the form of chemical reactions that produce new compounds with new properties entirely different from the material that composes them.
Therefore, the fields and interests of chemistry are various which made very important and widespread. With the development of the natural sciences, chemistry has significantly evolved after Dalton theory (the father of modern chemistry) followed by Bohr and Rutherford.
As a result of the continuous development of chemistry, the chemistry science was divided into four main sections namely, the organic chemistry, which is concerned with studying the materials that contain mainly carbon, inorganic chemistry, which is concerned with studying the materials consisted of natural elements and their properties, chemical physics, which is concerned with studying the physical properties of materials and attempting to understand the physical phenomena on chemical basis and finally, the analytical chemistry which is concerned with knowing the of materials components and origin.
