Rutherfordium - 104Rf: the essentials
Rutherfordium atoms have 104 electrons and the shell structure is 22.214.171.124.32.10.2. The ground state electronic configuration of neutral rutherfordium is [Rn].5f14.6d2.7s2 (a guess based upon that of hafnium) and the term symbol of rutherfordium is 3F2 (tentative).
Rutherfordium is a synthetic element that is not present in the environment at all. It has no uses.

Rutherfordium: historyRutherfordium was discovered by Workers at the Nuclear Institute at Dubna, and the University of California, Berkeley, USA. in 1964 at USSR, United States. Origin of name: the origin of the Amercian Chemical Society preferred name is Lord "Rutherford", the physicist and chemist from New Zealand..
Isolation: only very small amounts of of element 104, rutherfordium, have ever been made. The first samples were made through nuclear reactions involving fusion of an isotope of plutonium, 242Pu, with one of neon, 22Ne.
22Ne + 242Pu → 260104Rf + 4 1n
Isolation of an observable quantity of rutherfordium has never been achieved.
