Pure water (H 2 O) is an example of a compound. The ball-and-stick model of the molecule shows the spatial association of two parts hydrogen (white) and one part oxygen (red) A chemical compound is a chemical substance composed of many identical molecules (or molecular entities ) containing atoms from more than one chemical element held ...

Chemical classification systems attempt to classify elements or compounds according to certain chemical functional or structural properties. Whereas the structural properties are largely intrinsic, functional properties and the derived classifications depend to a certain degree on the type of chemical interaction partners on which the function is exerted.
The following are subcategories containing chemical compounds by element. An alternative listing of inorganic compounds may be found at inorganic compounds by element . Wikimedia Commons has media related to Chemical compounds by element .
an organic compound; simplest example of the ketones: Acetylene: a hydrocarbon and the simplest alkyne; widely used as a fuel and chemical building block Ammonia: inorganic; the precursor to most nitrogen-containing compounds; used to make fertilizer Ammonium hydroxide: aqueous ammonia; used in traditional qualitative inorganic analysis
Chemical formulas can be used to describe the relative amounts of elements present in a compound. For example, the chemical formula for water is H 2 O: this means that each molecule of water is constituted by 2 atoms of hydrogen (H) and 1 atom of oxygen (O). The chemical composition of water may be interpreted as a 2:1 ratio of hydrogen atoms ...
The similarity-based [4] virtual screening (a kind of ligand-based virtual screening) assumes that all compounds in a database that are similar to a query compound have similar biological activity. Although this hypothesis is not always valid, [ 5 ] quite often the set of retrieved compounds is considerably enriched with actives. [ 6 ]
