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 synthetic elements are those with atomic numbers 95–118, as shown in purple on the accompanying periodic table: [1] these 24 elements were first created between 1944 and 2010. The mechanism for the creation of a synthetic element is to force additional protons into the nucleus of an element with an atomic number lower than 95.
Promethium is not an easy image to find, however, out of all the elements without a picture, it is one of the two most likely to have a picture discovered. The only pictures floating around the place are of promethium chloride and promethium oxide, but not the metal itself. This is likely because the metal is not used for anything, it's hard to ...
James Andrew Harris (March 26, 1932 – December 12, 2000) was an American radiochemist who was involved in the discovery of elements 104 and 105 (rutherfordium and dubnium, respectively). Harris was the head of the Heavy Isotopes Production Group, part of the Nuclear Chemistry Division of the University of California, Berkeley .

Rutherfordium (104 Rf) is a synthetic element and thus has no stable isotopes. A standard atomic weight cannot be given. The first isotope to be synthesized was either 259 Rf in 1966 or 257 Rf in 1969. There are 17 known radioisotopes from 252 Rf to 270 Rf (three of which, 266 Rf, 268 Rf, and 270 Rf, are unconfirmed) and several isomers.
Organic compounds have one or more carbon atoms that are bound to other elements, usually hydrogen, oxygen, nitrogen and sulfur. All life on Earth is based on carbon and is built from organic ...
