Chemical compound

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

## Appearance and preparation

[edit]

Polonium monoxide is a black solid. It is formed during the radiolysis of polonium sulfite (PoSO3) and polonium selenite (PoSeO3).[1][2]

## Chemistry

[edit]

On contact with oxygen or water, both polonium monoxide and its related hydroxide (polonium(II) hydroxide, Po(OH)2) are oxidized quickly to Po(IV).[2]
