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 .
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.
