Periodic Table Group and Classification of the of the Rutherfordium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Rutherfordium 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 Discovery of the Rutherfordium Element and its other names
First synthesized at the Joint Nuclear Research Institute at Dubna, in Russia, in 1964 - leading to the name Dubnium (Db).
Rutherfordium 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 Unnilquadium (symbol Unq) as a temporary name
