Facts and Info about the element Argon - 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 Thallium 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. Thallium was discovered by Sir William Crookes in England in 1861. Claude-Auguste Lamy and Sir William Crookes isolated the metal independent of each other in 1862. 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 Thallium is just one element that can be found. |
