  2. Chemical compound - Wikipedia

    en.wikipedia.org/wiki/Chemical_compound

    Many chemical compounds have a unique numerical identifier assigned by the Chemical Abstracts Service (CAS): its CAS number. There is varying and sometimes inconsistent nomenclature differentiating substances, which include truly non-stoichiometric examples, from chemical compounds, which require the fixed ratios.

  5. Inorganic compound - Wikipedia

    en.wikipedia.org/wiki/Inorganic_compound

    All allotropes (structurally different pure forms of an element) and some simple carbon compounds are often considered inorganic. Examples include the allotropes of carbon ( graphite , diamond , buckminsterfullerene , graphene , etc.), carbon monoxide CO , carbon dioxide CO 2 , carbides , and salts of inorganic anions such as carbonates ...

    en.wikipedia.org/wiki/Glossary_of_chemical_formulae

    This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds . There is no complete list of chemical compounds since by nature the list would be infinite.

  7. Inorganic chemistry - Wikipedia

    en.wikipedia.org/wiki/Inorganic_chemistry

    Inorganic compounds exhibit a range of bonding properties. Some are ionic compounds, consisting of very simple cations and anions joined by ionic bonding.Examples of salts (which are ionic compounds) are magnesium chloride MgCl 2, which consists of magnesium cations Mg 2+ and chloride anions Cl −; or sodium hydroxide NaOH, which consists of sodium cations Na + and hydroxide anions OH −.

  8. Chemical substance - Wikipedia

    en.wikipedia.org/wiki/Chemical_substance

    All compounds are substances, but not all substances are compounds. A chemical compound can be either atoms bonded together in molecules or crystals in which atoms, molecules or ions form a crystalline lattice. Compounds based primarily on carbon and hydrogen atoms are called organic compounds, and all others are called inorganic compounds.

  9. 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.
