Chemistry is the science of matter and its interactions with energy (see physics, biology). Because of the diversity of matter (which is mostly atomic), Chemists are often engaged in the pursuit of studying how atoms interact to form molecules, and how molecules interact with each other.1 Branches of chemistry
Chemistry typically is divided into several main branches. There are also several main cross-disciplinary and more specialized branches of chemistry.
- Organic chemistry
- Organic chemistry is the science of the structure, properties, composition, and reactions of organic compounds.
- Inorganic chemistry
- Inorganic chemistry is the branch of chemistry concerned with the properties and reactions of inorganic compounds. The distinction between organic and inorganic disciplines is not absolute and there is much overlap, most importantly in the sub-discipline of organometallic chemistry.
- Physical chemistry
- Physical chemistry is the study of the physical basis of chemical systems and processes. In particular, the energetic description of diverse chemical transformations are of interest to physical chemists. Important areas of study include chemical thermodynamics, chemical kinetics, quantum chemistryQuantum chemistry is the application of quantum mechanics to problems in chemistry. The description of the electronic behavior of atoms and molecules as pertains to their reactivity is an application of quantum chemistry. Since quantum-mechanical studies, statistical mechanicsStatistical mechanics is the application of statistics, which includes mathematical tools for dealing with large populations, to the field of mechanics, which is concerned with the motion of particles or objects when subjected to a force. It provides a fr, and spectroscopySpectroscopy is the study of spectra, ie. the dependence of a physical measure to frequency. Spectroscopy is often used in physical and analytical chemistry for the identification of substances, through the spectrum emitted or absorbed. A device for recor.
- BiochemistryBiochemistry is the chemistry of life. Biochemists study the elements, compounds and chemical reactions that are controlled by enzymes and take place in all living organisms. Biochemistry is focused on the structure and function of cellular components, su
- Biochemistry is the study of the chemicalsA chemical compound is a substance formed from two or more elements, with a fixed ratio determining the composition. For example, dihydrogen monoxide ( water, ) is a compound composed of two hydrogen atoms for every oxygen atom. In general, this fixed rat, chemical reactions and chemical interactionGenerally, an interaction is a kind of action which occurs as two or more objects have an effect upon one another. The word is sometimes used synonymously with " transaction"; in some cases, a difference between the two should be distinguished. Examples is that take place in living organismIn biology and ecology, an organism is a living being. The origin of life and the relationships between its major lineages are controversial. Two main grades may be distinguished, the prokaryotes and eukaryotes. The prokaryotes are generally considered tos.
- Analytical chemistry
- Analytical chemistry is the analysis of material samples to gain an understanding of their chemical composition and structure.
