Chemistry is the branch of science that studies matter, that is to say properties, composition and structure of substances and the changes they undergo when they combine or react under specified conditions. Matter is anything that has mass and occupies space, anything we can touch or hold. Chemistry can be divided into fields, according to either the substances studied or the types of study conducted.
The primary division is between inorganic chemistry, the study of all the elements and their compounds with the exception of carbon and its compounds, and organic chemistry dealing with the compounds of carbon that forms the greatest number of different compounds.
More specifically, inorganic chemistry investigates the characteristics of substances that are not organic, such as nonliving matter and minerals found in the earth's crust. Fields of inorganic chemistry include applications such as in coordination chemistry, geochemistry, inorganic technology, nuclear science and energy. Organic chemistry is the branch of chemistry concerned with compounds of carbon and dealing with living matter. Most organic substances contain Hydrogen (H) and Carbon (C) and many contain Oxygen (O), Nitrogen (N), Sulphur (S) and Phosphorous (P).These and other elements are normally bonded to carbon by covalent bonds as opposed to ionic bonds which are typical of inorganic compounds. Because of the extraordinary bonding properties of carbon, there are more organic compounds than inorganic compounds.
Today, there are many areas where these two fields of chemistry overlap. For example, organometallic chemistry looks at compounds in which carbon - normally studied by organic chemists - bonds with a metal - normally studied by inorganic chemists.
Another classification can imply the distinction between Physical Chemistry, concerned with the physical properties of materials, such as their electrical and magnetic behavior and their interaction with electromagnetic fields, and Analytical Chemistry consisting in a collection of techniques that allows exact laboratory determination of the composition of a given sample of material.
