    en.wikipedia.org/wiki/Carbon

    Carbon (from Latin carbo 'coal') is a chemical element; it has symbol C and atomic number 6. ... The physical properties of carbon vary widely with the allotropic form.

  3. 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.

  4. Allotropes of carbon - Wikipedia

    en.wikipedia.org/wiki/Allotropes_of_carbon

    Carbon nanotubes, also called buckytubes, are cylindrical carbon molecules with novel properties that make them potentially useful in a wide variety of applications (e.g., nano-electronics, optics, materials applications, etc.). They exhibit extraordinary strength, unique electrical properties, and are efficient conductors of heat.

  5. Carbon-based life - Wikipedia

    en.wikipedia.org/wiki/Carbon-based_life

    Carbon atoms bond readily to other carbon atoms; this allows the building of arbitrarily long macromolecules and polymers in a process known as catenation. [ 20 ] [ 21 ] [ 22 ] "What we normally think of as 'life' is based on chains of carbon atoms, with a few other atoms, such as nitrogen or phosphorus", per Stephen Hawking in a 2008 lecture ...

    The carbon group is a periodic table group consisting of carbon (C), silicon (Si), ... element that may have a few noble gas-like properties, though it is still most ...

  7. Isotopes of carbon - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_carbon

    Carbon (6 C) has 14 known isotopes, from 8 C to 20 C as well as 22 C, of which 12 C and 13 C are stable.The longest-lived radioisotope is 14 C, with a half-life of 5.70(3) × 10 3 years. . This is also the only carbon radioisotope found in nature, as trace quantities are formed cosmogenically by the reactio

  8. Atomic carbon - Wikipedia

    en.wikipedia.org/wiki/Atomic_carbon

    Atomic carbon, systematically named carbon and λ 0-methane, is a colourless gaseous inorganic chemical with the chemical formula C (also written [C]). It is kinetically unstable at ambient temperature and pressure, being removed through autopolymerisation.

  9. Carbon monoxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_monoxide

    Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is ...
