Chemistry is the scientific study of matter and the changes in the states of matter. It involves the physical study of chemical compounds and their atomic and molecular structures, as well as the principles of energy and entropy and how these affect chemical processes. Chemistry is a complex subject requiring many skills, from understanding the underlying basis of chemical reactions to how those microscopic reactions can affect the world on a global scale. Chemistry also requires an knowledge of chemical symbols and equations, the use of modeling techniques in new discoveries and how to demonstrate theoretical chemistry through practical experimentation.
Chemistry contains many different fields of specialization. Inorganic chemistry deals with the nature and behavior of the majority of chemical compounds, except for carbon-based compounds, which are studied in organic chemistry. Physical chemistry is the study of the chemical reactions of particles of matter down to the subatomic level. Biochemistry analyzes the chemical processes that occur in living organisms, while analytical chemistry involves separating, identifying and measuring chemical compounds. For people interested in discovering more about this varied and vital field of science, here are a collection of resources on many aspects of chemistry.
