WebPolonium werd ontdekt door Marie Curie, de bekende Poolse scheikundige, in 1898. Ze verkreeg polonium uit pitchblende, een materiaal dat uranium bevat, nadat ze ontdekte dat onbewerkt pitchblende meer radioactief was dan het uranium dat eruit werd gewonnen. Ze bedacht dat pitchblende dus in ieder geval een ander radioactief element moest bevatten. WebPolonium ist das chemische Element mit der Ordnungszahl 84. Es ist ein silbriges, radioaktives Metall, das sich in chemischen Reaktionen ähnlich verhält wie Tellur und Bismut. Stabile Polonium- Isotope gibt es nicht. In der Natur ist Polonium-210 das am häufigsten vorkommende Polonium-Isotop.
