  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 - Wikipedia

    en.wikipedia.org/wiki/Carbon

    Carbon's abundance, its unique diversity of organic compounds, and its unusual ability to form polymers at the temperatures commonly encountered on Earth, enables this element to serve as a common element of all known life. It is the second most abundant element in the human body by mass (about 18.5%) after oxygen.

  4. List of chemical elements - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_elements

    List of chemical elements. 118 chemical elements have been identified and named officially by IUPAC. A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z ). [ 1]

  5. 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.

  6. Carbon group - Wikipedia

    en.wikipedia.org/wiki/Carbon_group

    Carbon, the lightest carbon group element, sublimes at 3825 °C. Silicon's boiling point is 3265 °C, germanium's is 2833 °C, tin's is 2602 °C, and lead's is 1749 °C. Flerovium is predicted boil in -60 °C. [11] [12] The melting points of the carbon group elements have roughly the same trend as their boiling points. Silicon melts at 1414 °C ...

  7. Carbon-based life - Wikipedia

    en.wikipedia.org/wiki/Carbon-based_life

    In a 2018 study, carbon was found to compose approximately 550 billion tons of all life on Earth. [ 16][ 17] It is the second most abundant element in the human body by mass (about 18.5%) after oxygen. [ 18] The most important characteristics of carbon as a basis for the chemistry of cellular life are that each carbon atom is capable of forming ...

  8. Carbon–carbon bond - Wikipedia

    en.wikipedia.org/wiki/Carboncarbon_bond

    Carbon is one of the few elements that can form long chains of its own atoms, a property called catenation.This coupled with the strength of the carboncarbon bond gives rise to an enormous number of molecular forms, many of which are important structural elements of life, so carbon compounds have their own field of study: organic chemistry.

  9. Organic compound - Wikipedia

    en.wikipedia.org/wiki/Organic_compound

    The modern, commonly accepted definition of organic compound essentially amounts to any carbon-containing compound, excluding several classes of substances traditionally considered "inorganic". The list of substances so excluded varies from author to author. Still, it is generally agreed upon that there are (at least) a few carbon-containing ...
