Periodic Table Group and Classification of the of the Hafnium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Hafnium is classified as a "Transition Metal" which are located in Groups 3 - 12 of the Periodic Table. Elements classified as Transition Metals are generally described as ductile, malleable, and able to conduct electricity and heat.Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals.
Facts about the History and the Discovery of the Hafnium Element
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.
