Rutherfordium is a chemical element with atomic number 104, it is one of the transactinoids.

All seven known isotopes of rutherfordium are radioactive.

The element was discovered in 1964 at the nuclear research center near Dubna (Soviet Union) after bombarding plutonium with neon nuclei. After the discovery, there was an element naming controversy and it was not until 1997 that a decision was made to name it after Ernest RutherfordRutherfordium to call.

Another name that was used at times for this element, and still appears in some older tables, is Kurchatovium (or English Kurchatovium) (Ku, after Igor Wassiljewitsch Kurchatow).
