Monoxide PbO are amphoteric. Monoxide A monoxide is any oxide containing just one atom of oxygen in the molecule. For example, Potassium oxide (KO), has only one atom of oxygen, and is thus a monoxide. Water (HO) is also a monoxide; see dihydrogen monoxide hoax. A well known monoxide is carbon monoxide (CO); see carbon monoxide poisoning. Most of the members of the Periodic Table form oxides when oxidized. There are two main types of oxides: monoxides and dioxides. Monoxides (generally MO) such as silicon monoxide (SiO) only exist at high temperatures. Among monoxides, CO is neutral, GeO is distinctly acidic,
Holmium(III) oxide Holmium(III) oxide Holmium(III) oxide, or holmium oxide is a chemical compound of a rare-earth element holmium and oxygen with the formula HoO. Together with dysprosium(III) oxide (DyO) holmium oxide is one of the most powerfully paramagnetic substances known. The oxide, also called holmia, occurs as a component of the related erbium oxide mineral called erbia. Typically the oxides of the trivalent lanthanides coexist in nature and separation of these components requires specialized methods. Holmium oxide is used in making specialty colored glasses. Glass containing holmium oxide and holmium oxide solutions have a series of sharp optical absorption peaks in the
