  3. Carbon - Wikipedia

    en.wikipedia.org/wiki/Carbon

    The atoms of carbon can bond together in diverse ways, resulting in various allotropes of carbon. Well-known allotropes include graphite, diamond, amorphous carbon, and fullerenes. The physical properties of carbon vary widely with the allotropic form. For example, graphite is opaque and black, while diamond is highly transparent. Graphite is ...

    en.wikipedia.org/wiki/Atom

    To visualize the minuteness of the atom, consider that a typical human hair is about 1 million carbon atoms in width. [77] A single drop of water contains about 2 sextillion (2 × 10 21) atoms of oxygen, and twice the number of hydrogen atoms. [78] A single carat diamond with a mass of 2 × 10 −4 kg contains about 10 sextillion (10 22) atoms ...

  5. Lists of molecules - Wikipedia

    en.wikipedia.org/wiki/Lists_of_molecules

    This is an index of lists of molecules (i.e. by year, number of atoms, etc.). Millions of molecules have existed in the universe since before the formation of Earth. Three of them, carbon dioxide, water and oxygen were necessary for the growth of life.

  6. Organic compound - Wikipedia

    en.wikipedia.org/wiki/Organic_compound

    Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carboncarbon bond; others consider an organic compound to be any chemical compound that contains carbon. For example, carbon-containing compounds such as alkanes (e.g. methane CH 4) and its derivatives are universally considered ...

  7. Carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide

    Carbon dioxide is the lasing medium in a carbon-dioxide laser, which is one of the earliest type of lasers. Carbon dioxide can be used as a means of controlling the pH of swimming pools, [139] by continuously adding gas to the water, thus keeping the pH from rising. Among the advantages of this is the avoidance of handling (more hazardous) acids.

  9. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    One or more of the hydrogen atoms can be replaced with other atoms, for example chlorine or another halogen: this is called a substitution reaction. An example is the conversion of methane to chloroform using a chlorination reaction. Halogenating a hydrocarbon produces something that is not a hydrocarbon. It is a very common and useful process.
