Facts about the Definition of the Element Hafnium
The Element Hafnium is defined as...
A brilliant, silvery, metallic element separated from ores of zirconium and used in nuclear reactor control rods, as a getter for oxygen and nitrogen, and in the manufacture of tungsten filaments. The most common uses of Hafnium are in Nuclear reactors, Hafnium reactor, the Hafnium bomb, used in incandescent lamps and Tungsten filaments
Interesting Facts about the Origin and Meaning of the element name Hafnium
What are the origins of the word Hafnium ?
The word Hafnium originates from the Latin Hafnia for "Copenhagen".
Facts about the Classification of the Element Hafnium
Hafnium is classified as a "Transition Metal" which are located in Groups 3 - 12 of the Periodic Table. An Element classified as a Transition Metals is ductile, malleable, and able to conduct electricity and heat.
Brief Facts about the Discovery and History of the Element Hafnium
Hafnium was discovered by Dirk Coster and Georg von Hevesy in 1923 in Copenhagen, Denmark. Found in zircon through X-ray spectroscope analysis in Norway. First separated from zirconium through re-crystallization of double ammonium or potassium fluorides by Jantzen and von Hevesey. Metallic Hafnium was first prepared by Anton Eduard van Arkel and Jan Hendrik deBoer. Associated with zirconium by using the Bohr theory.

Facts and Info about the element Hafnium - 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 Hafnium 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. Hafnium was discovered by Dirk Coster and Georg von Hevesy in 1923 in Copenhagen, Denmark. Found in zircon through X-ray spectroscope analysis in Norway. First separated from zirconium through re-crystallization of double ammonium or potassium fluorides by Jantzen and von Hevesey. Metallic Hafnium was first prepared by Anton Eduard van Arkel and Jan Hendrik deBoer. 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 Hafnium is just one element that can be found.
