Sodium polonide is a radioactive chemical compound with the formula Na2Po. This salt is a polonide, a set of very chemically stable compounds of polonium.[2][3] Due to the difference in electronegativity (ΔEN) between sodium and polonium (≈ 1.1 under the Pauling system) and the slight non-metallic character of polonium, it is intermediate between intermetallic phases and ionic compounds.
