A chemical element, in the periodic table polonium has the symbol Po and atom number 84. Polonium has more isotopes than any other element, all of which are radioactive. It dissolves readily in dilute acids, but is only slightly soluble in alkalis. Weight for weight polonium is about 2.5 x 10 times as toxic as hydrocyanic acid (HCN). Polonium has been found in tobacco as a contaminant and in uranium ores.
Discovered by Marie Sklodowska-Curie in 1898 and named after her home country - Poland.
