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