Polonium metal has a melting point of 254°C (489°F), a boiling point of 962°C (1,764°F), and a density of 9.4 grams per cubic centimeter. Chemical properties Polonium has chemical properties like the elements above it in the periodic table, especially selenium and tellurium. Poloni...
The properties of astatine are not well known. The element breaks down too fast to allow experiments that take more than a few hours. No melting point, boiling point, or density is specified for astatine. The most complete experiments on astatine were begun in 1966 at the Argonne National La...
