Compounds
Chemical compounds are pure chemical substances consisting of two or more different chemical elements that cannot be separated into simpler substances and that have a unique and defined chemical structure. Chemical compounds consist of a fixed ratio of atoms that are hold together in a defined spatial arrangement by chemical bonds. Chemical compounds can be compound molecules hold together by covalent bonds, salts hold together by ionic bonds, metallic compounds hold together by metallic bonds, and complexes hold together by coordinate covalent bonds. Substances such as pure chemical elements and elemental molecules consisting of only a single atom type are not considered chemical compounds.
Examples of compounds are : water , table salt , sodium chloride .
