Polonium is a chemical element with the symbol Po and atomic number 84. A rare and highly radioactive metal with no stable isotopes, polonium is chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbors in the periodic table: thallium, lead, and bismuth.

www.poloniumfoundation.org The Nobel Prize in Chemistry 1911 was awarded to Marie Curie, née Sklodowska "in recognition of her services to the advancement of chemistry by the discovery of the elements radium and polonium, by the isolation of radium and the study of the nature and compounds of this remarkable element". Dec 6, 2018 Polonium (Po) is a very rare and highly volatile radioactive metal. Before Polish- French physicist Marie Curie's discovery of polonium in 1898,  Nov 29, 2006 Polonium-210, the radioactive isotope fingered as the substance used to off exiled Russian KGB spy Alexander Litvinenko, is available to buy  Polonium is a radioactive element, meaning it sends out energy in the form of rays, waves or particles.

Nov 29, 2012 A dangerous dose of polonium-210 can be a matter of micrograms -- smaller than a single speck of pepper, an expert says.

Polonium has no stable isotopes and is only found in nature in trace amounts as a radioactive decay product in some radioactive minerals. General Properties.
