Hydrogen polonide, H2Po, is the heaviest of the chalcogen hydrides. It has been prepared in trace quantities by the reduction of polonium with magnesium in dilute hydrochloric acid.[1] Its physical properties are unknown but, by comparison with other chalcogen hydrides, it is expected to be a volatile liquid at room temperature.[2][3] It is thought to be implicated in the bio-volatization of polonium, leading to a relative excess of polonium in the atmosphere compared with open ocean waters.[4]
