History & Etymology

First preparation by Russian and American teams:

  • 1964 by Г.Н. Флеров (Georgy Nikolaevich Flerov), Юрий Цолакович Оганесян (Yuri Tsolakovich Oganessian), Ю.В. Лобанов (Yu.V. Lobanov), V.I. Kuznetsov, V.A. Druin, V.P. Perelygin, K.A. Gavrilov, C.П. Третьякова (S.P. Tretiakova), and V.M. Plotko at the Объединенный Институт Ядерных Исследований (ОИЯИ) - Joint Institute for Nuclear Research (JINR) at Дубна (Dubna), Russia, by bombardment of Plutonium with Neon ions and named Курчатовий (Kurchatovium) (Ku) after Igor Vasilevitch Kurchatov (1903-1960), head of the Soviet Nuclear Research.
  • 1969 by Albert Ghiorso, M. Nurmia, J. Harris, K. Eskola and P. Eskola at the Berkeley Laboratory of the University of California by bombardment of Californium with Carbon ions and named Rutherfordium.

The systematic IUPAC name was Unnilquadium (Unq). In 1994 IUPAC proposed the name Dubnium because it was first discovered at (Dubna) (cf. Dubnium). The American Chemical Society proposed Rutherfordium, the name given by Ghiorso a.o. in 1969. The latter became also the current IUPAC name. Dubnium was then used for element 105. The name and symbol Rutherfordium (Rf) was ratified by the International Union of Pure and Applied Chemistry (IUPAC) Council meeting in Geneva during August 1997 (See "Naming the transfermium elements").

Ernest Rutherford
Ernest Rutherford, 1e Baron Rutherford of Nelson (Brightwater, New Zealand, 30 augustus 1871 - Cambridge, England, 19 October 1937). New Zealand chemist and physicist who became known as the father of nuclear physics. He discovered that atoms have their positive charge concentrated in a very small nucleus, and thereby pioneered the Rutherford model, or planetary, model of the atom, through his discovery and interpretation of Rutherford scattering in his gold foil experiment. He was awarded the Nobel Prize in Chemistry in 1908. He is widely credited as splitting the atom in 1917 and leading the first experiment to "split the nucleus" in a controlled manner by two students under his direction, John Cockcroft and Ernest Walton in 1932 (note).

Igor Kurchatov
Igor Vasilyevich Kurchatov (Russian: И́горь Васи́льевич Курча́тов 12 January 1903 7 February, 1960), Soviet/Russian nuclear physicist. He was the leader of the Soviet atomic bomb project. He was one of the central figures in the Soviet nuclear program. He is best known for his role as a director of the nascent Soviet nuclear program. He led a team of Soviet scientists in developing and building a nuclear weapon program. Under his direction the Soviet Union successfully tested its first plutonium-based nuclear device, First Lightning in 1949. For this reason he is remembered as "The Father of the Soviet Atomic Bomb". (note).
