Rutherfordium is a radio active atom that was obtained by nuclear fusion techniques. It does not occur in nature.

What the name means: The Russian group named element # 104 kurchatovium (Ku). However, the American group in Berkeley had named element # 104 rutherfordium after the New Zealand-born scientist, Ernest Rutherford.
The International Union of Pure and Applied Chemistry (IUPAC)  temporarily named the new element Unnilquadium, with the symbol Unq. In 1997 the IUPAC upheld the name rutherfordium (Rf).

Who made rutherfordium?: Georgy Nikolaevich Flerov and  co-workers at the Joint Institute for Nuclear Research in Dubna, Russia in 1964.

About  rutherfordium: Rutherfordium was made by the Russian team by bombarding plutonium atoms with neon nuclei. In 1969, the American team at Berkeley used californium atoms bombarded by carbon nuclei. Only a few atoms of rutherfordium have ever been made.
