Rutherfordium is a synthetic chemical element; it has symbol Rf and atomic number 104. It is named after physicist Ernest Rutherford. As a synthetic element, it is not found in nature and can only be made in a particle accelerator. It is radioactive; the most stable known isotope, 267 Rf, has a half-life of about 48 minutes.
When IUPAC made the final decision of the naming of the elements beyond 100 in 1997, it decided to keep the name "lawrencium" and symbol "Lr" for element 103 as it had been in use for a long time by that point. The name "rutherfordium" was assigned to the following element 104, which the Berkeley team had proposed it for. [43]
The chemical element rutherfordium (104 Rf) was named after him in 1997. Early life and education Ernest Rutherford was born on 30 August 1871 in Brightwater , a town near Nelson , New Zealand. [ 14 ]
An international committee decided in 1992 that the Berkeley and Dubna laboratories should share credit for the discovery. An element naming controversy erupted and as a result IUPAC adopted unnilhexium (Unh) as a temporary systematic element name. In 1994, a committee of IUPAC adopted a rule that no element can be named after a living person. [15]
41 of the 118 known elements have names associated with, or specifically named for, places around the world or among astronomical objects. 32 of these have names tied to the places on Earth, and the other nine are named after to Solar System objects: helium for the Sun; tellurium for the Earth; selenium for the Moon; mercury (indirectly), uranium, neptunium and plutonium after their respective ...
Low oxidation states are not well-represented for zirconium and hafnium [28] (and should be even less well-represented for rutherfordium); [30] the +3 oxidation state of zirconium and hafnium reduces water. For titanium, this oxidation state is merely easily oxidised, forming a violet Ti 3+ aqua cation in solution. The elements have a ...
rutherfordium, Rf, named after Ernest Rutherford, who was responsible for the concept of the atomic nucleus (1969). This discovery was also claimed by JINR, led principally by Georgy Flyorov: they named the element kurchatovium (Ku), after Igor Kurchatov. IUPAC concluded that credit should be shared, and adopted the LBNL name rutherfordium. 105.
As of 1 Jan 2023, elements E119 and higher are not discovered. These are called theoretical elements. They can have article and other content pages though. Incidentally, this concerns period 8 completely. For the Infobox <element>, their redirected pages do not count (are treated as: "R page does not exist").
