Facts and Info about the element Protactinium - IUPAC and the Modern Standardised Periodic Table The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 which includes the Protactinium element. The famous Russian Scientist, Dimitri Mendeleev, perceived the correct classification method of "the periodic table" for the 65 elements which were known in his time. Protactinium was discovered by Fredrich Soddy in 1917. The Standardised Periodic Table now recognises more periods and elements than Dimitri Mendeleev knew in his day but still all fitting into his concept of the "Periodic Table" in which Protactinium is just one element that can be found. |
