Polonium monoxide (also known as polonium(II) oxide) is a chemical compound with the formula {{chem2|PoO|auto=yes}}. It is one of three oxides of polonium, the other two being polonium dioxide ({{chem2|PoO2}}) and polonium trioxide ({{chem2|PoO3}}). It is an interchalcogen.

Appearance and preparation

Polonium monoxide is a black solid. It is formed during the radiolysis of polonium sulfite ({{chem2|PoSO3}}) and polonium selenite ({{chem2|PoSeO3}}).

Chemistry

On contact with oxygen or water, both polonium monoxide and its related hydroxide (polonium(II) hydroxide, {{chem2|Po(OH)2}}) are oxidized quickly to polonium dioxide.
