WebElements Periodic Table of the Elements | Polonium

Chemical reactions of the elements

Reaction of polonium with air

Polonium burns in air to form the solid dioxide polonium(IV) oxide, PoO₂.

Po(s) + 2O₂(g) → PO₂(s)

Reaction of polonium with water

Reaction of polonium with the halogens

Polonium reacts under controlled conditions with the halogens chlorine, Cl₂, bromine, Br₂, and iodine, I₂, to form the respective tetrahalides polonium(IV) chlrode, polonium(IV) bromide, and polonium(IV) iodide.

Po(s) + 2Cl₂(g) → PoCl₄(s) [yellow]

Po(s) + 2Br₂(g) → PoBr₄(s) [red]

Po(s) + 2I₂(g) → PoI₄(s) [black]

Reaction of polonium with acids

Polonium dissolves in concentrated hydrochloric acid, HCl, sulphuric acid, H₂SO₄, or concentrated nitric acid, HNO₃, initially to form solutions containing Po(II).
