Hydrogen polonide (more correctly polonium hydride or polane) is a chemical compound with the formula H2Po. It is a more covalent compound than most metal hydrides because polonium is more like a nonmetal. It is intermediate with a hydrogen halide like hydrogen chloride and a metal hydride like stannane.
It should have properties similar to that of hydrogen telluride and hydrogen selenide, other borderline hydrides. It is not stable at room temperature and must be stored at freezer temperatures to prevent reversion to elemental polonium and hydrogen. It is difficult to work with due to the extreme radioactivity of polonium and its compounds and has only been prepared in very dilute tracer quantities. As a result its physical properties are not definitely known.[1] It would be acidic if dissolved in water, forming a solution of hydropolonic acid, although this experiment would be almost impossible to do because of the instability and radioactivity of polonium.
