Chemistry is the science that deals with the composition and structure of matter and with the changes matter undergoes.
Chemistry is a branch of science that has been around for a long time. In fact, chemistry is known to date back to as far as the prehistoric times. By 4000 BC Europe obtained this culture but by this time in Egypt and Sumeria (Iraq) metals were being used. The name of chemistry is derived from the Arabic word al-Kimya.
Alchemists are the old chemists who are not only wanted to convert metals to gold, but they also wanted to find a mixture of chemical that would enable people to live longer and cure all illnesses.
Today chemistry is an important and exciting subject. It is all around you; in houses, fairgrounds, fields, farms, and factories. It is taking place deep in the Earth and far out in space. You will find chemistry everywhere.
Why do we study chemistry?
Because we may say that "life is chemistry". Chemistry is in each point of our daily life. You may not realize it, but chemistry is all around you. Dye, plastic, cosmetic, medicine, cleaning product, textile, paper, photography, firework, weapon, fuel, glass and metallurgy are some industries interested in chemistry.
Chemistry, physics, biology and earth science are four main branches of natural sciences. Each of the branches of natural science has its own area that is closely related o each other. No branch of science can be entirely independent of others.
Chemistry has six main branches which are analytical chemistry, physical chemistry, inorganic chemistry, organic chemistry, bio-chemistry and nuclear chemistry.
Analytical Chemistry: (Separation, identification, and composition of matter)
Organic Chemistry: (Carbon and carbon containing materials)
Physical Chemistry: (Investigation of the laws and theories of all branches of chemistry)
Biochemistry: (Materials and processes that occur in living organisms)
Inorganic Chemistry: (Elements and their compounds)
Nuclear Chemistry: (Changes in the nuclei of atoms and the uses of these changes)
