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.
The Joint Institute for Nuclear Research in Dubna (then USSR, today Russia) named element 104 kurchatovium (Ku) in honor of Igor Kurchatov, father of the Soviet atomic bomb, while the University of California, Berkeley, US, named element 104 rutherfordium (Rf) in honor of Ernest Rutherford.
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 ...
This list of chemical elements named after places includes elements named both directly and indirectly for places. 41 of the 118 chemical elements have names associated with, or specifically named for, places around the world or among astronomical objects.
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]
Elements which are named after currently existing countries and cities are as: Polonium, named after Poland [15] Francium and gallium, both named after France [16] Nihonium, named after Japan; Germanium was named for Germany [17] Beryllium was named after the mineral beryl, whose name may have come from Belur, a city in Karnataka state of India ...

In 1997 the International Union of Pure and Applied Chemistry settled the dispute: element 104 was given the name suggested by the American research team, rutherfordium, after the influential British physicist. Element 105 was subsequently given the name dubnium, representing the city, Dubna, where the Russian team worked. [10]
