3. Chemical compound - Wikipedia

   en.wikipedia.org/wiki/Chemical_compound

   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 ...

4. Molecule - Wikipedia

6. List of chemical classifications - Wikipedia

   en.wikipedia.org/wiki/List_of_chemical...

   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.

   Single atom anions are named with an -ide suffix: for example, H − is hydride. Compounds with a positive ion : The name of the compound is simply the cation's name (usually the same as the element's), followed by the anion. For example, NaCl is sodium chloride, and CaF 2 is calcium fluoride.

8. List of chemical elements - Wikipedia

   en.wikipedia.org/wiki/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).

9. Chemical composition - Wikipedia

   en.wikipedia.org/wiki/Chemical_composition

   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 ...
