supports: Marguerite Catherine Perey ( 19 October 1909 -- 13 May 1975 ) was a French physicist and a student of Marie Curie . In 1939 , Perey discovered the element francium by purifying samples of lanthanum that contained actinium . In 1962 , she was the first woman to be elected to the French Académie des Sciences , an honor denied to her mentor Curie . Perey died of cancer in 1975 . The University of Paris, metonymically known as the Sorbonne (its historical house), was a university in Paris, France. Appearing around 1150 as a corporation associated with the Notre Dame de Paris cathedral school, it was the second-oldest modern university in Europe. Chartered in 1200 by King Philip II (Philippe-Auguste) of France and recognised in 1215 by Pope Innocent III, it was often nicknamed after its theology collegiate institution, College of Sorbonne, founded about 1257 by Robert de Sorbon. Polonium is a chemical element with 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 it also shows resemblances to its horizontal neighbors thallium, lead, and bismuth due to its metallic character. Due to the short half-life of all its isotopes, its natural occurrence is limited to tiny traces of the fleeting polonium-210 (with a half-life of 138 days) in uranium ores, as it is the penultimate daughter of natural uranium-238. Though slightly longer-lived isotopes exist, they are much more difficult to produce. Today, polonium is more often produced in milligram quantities by the neutron irradiation of bismuth. Due to its intense radioactivity, which results in radiolysis of chemical bonds and immense radioactive self-heating, its chemistry has mostly been investigated on the trace scale only. Marie Skodowska Curie (; 7 November 18674 July 1934), born Maria Salomea Skodowska , was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. She was the first woman to win a Nobel Prize, the first person and only woman to win twice, the only person to win a Nobel Prize in two different sciences, and was part of the Curie family legacy of five Nobel Prizes. She was also the first woman to become a professor at the University of Paris, and in 1995 became the first woman to be entombed on her own merits in the Panthéon in Paris. Actinium is a radioactive chemical element with symbol Ac (not to be confused with the abbreviation for an acetyl group) and atomic number 89, which was discovered in 1899. It was the first non-primordial radioactive element to be isolated. Polonium, radium and radon were observed before actinium, but they were not isolated until 1902. Actinium gave the name to the actinide series, a group of 15 similar elements between actinium and lawrencium in the periodic table. It is also sometimes considered the first of the 7th-period transition metals, although lawrencium is less commonly given that position.
