ox·ide | ˈäk-ˌsīd
noun
A compound containing one oxygen atom per molecule
Oxide is any chemical compound that contains exactly one oxygen atom in each molecule. Oxygen is a unique element that is able to form a stable chemical bond with almost all types of other elements. There are some noble metals, however, that are resistant to oxidation and are prized because of it - gold and platinum are two such metals. One of the most common oxides in relation to metal is iron oxide, or rust, which is the result of hydrated iron oxides. There are many forms of oxide that can occur in relation to jewelry. This oxidation process can blacken or tarnish the metal over time if it is not properly cared for and cleaned.
