Brief Facts about the Discovery and History of the Element Dubnium
Dubnium was first synthesized at the Joint Nuclear Research Institute at Dubna, in Russia, in 1964 - leading to the name Dubnium. Also known as Rutherfordium which was synthesized by Albert Ghiorso in 1969 at the University of California and named in honor of Ernest Rutherford, a New Zealand chemist and physicist. Also named as Kurchatovium (Ku) in honor of Igor Vasilevich Kurchatov (1903-1960) the former Head of Soviet Nuclear Research. IUPAC - the International Union of Pure and Applied Chemistry adopted Unnilpentium (Unp) as a temporary name. Also known as Joliotium (Jl) and Hahnium (Ha) after the German scientist Otto Hahn

Facts and Info about the element Dubnium - 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 Dubnium 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. Dubnium was first synthesized at the Joint Nuclear Research Institute at Dubna, in Russia, in 1964 - leading to the name Dubnium. 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 Dubnium is just one element that can be found.
