Resource · Periodic Table; Tellurium and Polonium Polonium (Po) chemical structure, technical & safety data, discovery, uses. Periodic table of the elements, materials science and academic information, Two new elements in Mendelyev's periodic table. The hangar on rue Lhomond. Pierre and Marie Curie in 1898, in the 'discovery hangar' at the Ecole de Group 6A (or VIA) of the periodic table are the chalcogens: the nonmetals oxygen and selenium (Se), the metalloid tellurium (Te), and the metal polonium (Po). Polonium is a rare and highly volatile radioactive element.
Polonium was the first element discovered by Mme. Curie in 1898, while seeking the cause of radioactivity of pitchblende from Joachimsthal, Bohemia. The electroscope showed it separating with bismuth. Polonium is also called Radium F. Polonium is a very rare natural element. Uranium ores contain only about 100 μg of the element per ton.
