chemical compound

Quick Summary

A chemical compound is a substance formed when atoms of two or more different chemical elements bond together. These compounds are made up of identical molecules, with the formula indicating the types of atoms and their relative numbers. For example, water (H₂O) is a compound of hydrogen and oxygen.1

Binary compounds are the simplest type, consisting of only two elements. Binary molecular (covalent) compounds are formed from two nonmetals. They are named by stating the first element's name, followed by the second element named as if it were an anion, with prefixes indicating the number of atoms of each element. For instance, CO is carbon monoxide.2

Compounds can also be classified as organic or inorganic. Inorganic compounds typically do not contain carbon-carbon bonds, while organic compounds usually do.21
