  2. Carbon compounds - Wikipedia

    en.wikipedia.org/wiki/Carbon_compounds

    Carbon compounds are defined as chemical substances containing carbon. [ 1][ 2] More compounds of carbon exist than any other chemical element except for hydrogen. Organic carbon compounds are far more numerous than inorganic carbon compounds. In general bonds of carbon with other elements are covalent bonds.

  3. Carbon-based life - Wikipedia

    en.wikipedia.org/wiki/Carbon-based_life

    Carbon-based life. The Lewis structure of a carbon atom, showing its four valence electrons. Carbon is a primary component of all known life on Earth, and represents approximately 45–50% of all dry biomass. [ 1] Carbon compounds occur naturally in great abundance on Earth.

  4. Carbon - Wikipedia

    en.wikipedia.org/wiki/Carbon

    Carbon-based compounds form the basis of all known life on Earth, and the carbon-nitrogen-oxygen cycle provides a small portion of the energy produced by the Sun, and most of the energy in larger stars (e.g. Sirius). Although it forms an extraordinary variety of compounds, most forms of carbon are comparatively unreactive under normal conditions.

  5. Carbon group - Wikipedia

    en.wikipedia.org/wiki/Carbon_group

    Carbon is a key element to all known life. It is in all organic compounds, for example, DNA, steroids, and proteins. [6] Carbon's importance to life is primarily due to its ability to form numerous bonds with other elements. [17] There are 16 kilograms of carbon in a typical 70-kilogram human. [18] Silicon-based life's feasibility is commonly ...

  6. Halocarbon - Wikipedia

    en.wikipedia.org/wiki/Halocarbon

    Halocarbon. Halocarbon compounds are chemical compounds in which one or more carbon atoms are linked by covalent bonds with one or more halogen atoms ( fluorine, chlorine, bromine or iodine – group 17) resulting in the formation of organofluorine compounds, organochlorine compounds, organobromine compounds, and organoiodine compounds.

  7. Organic chemistry - Wikipedia

    en.wikipedia.org/wiki/Organic_chemistry

    Category. v. t. e. Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [ 1] Study of structure determines their structural formula.

  8. Organic matter - Wikipedia

    en.wikipedia.org/wiki/Organic_matter

    Organic matter. Organic matter, organic material, or natural organic matter refers to the large source of carbon-based compounds found within natural and engineered, terrestrial, and aquatic environments. It is matter composed of organic compounds that have come from the feces and remains of organisms such as plants and animals. [ 1]

  9. Carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Carbon_cycle

    The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth. Other major biogeochemical cycles include the nitrogen cycle and the water cycle. Carbon is the main component of biological compounds as well as a major component of many ...
