Chemistry is a natural science which scrutinizes matter. The springs of today's chemistry have come from the old times. It used to be named alchemy - there were the attempts to turn iron into gold. Nowadays chemistry just scrutinizes the ingredients of various substances, their atomic levels and the reactions that happen while different substances are being combined. That is also quite important to detect the laws to have the possibility to generate the required matters from other ones. To execute the chemical researches, that is necessary to be good in physics and biology.

Inorganic chemistry, organic chemistry analytical chemistry, physical and biological chemistry are the parts of general definition “Chemistry”.

As the scientists had the thoughts that the organic elements have the connections to the life organisms the organic chemistry was named this way. But modern science has proved that not all the elements of organic chemistry are connected to the life and living organisms. Some inorganic elements as cooper or iron, for instance, play the main role in the in the reactions of living objects.

The substances which include carbon and hydrogen are the first objects of experiments provided by organic chemistry. Their features are studied in detail and the outcomes of analysis are quite helpful. A great deal of different products which we utilize in daily life has been invented with help of organic components.

The sphere of chemistry which studies the combinations of both organic and inorganic components is named analytical chemistry. The molecules and atoms of the substance are studied in details by that science. It researches the components given, their composition and features. Analytical and physical chemistry are very similar, because they research the same reactions but gain some different information from them. The scientists who work in that field give much for the saving of natural resources and the defense of the environment.
