Rutherfordium

Rutherfordium (Rf) is a radioactive metal that has the atomic number 104 in the periodic table, its appearance is not fully known due to the minuscule amounts produced of it. It is a Transition metal in Group 4. It has the symbol Rf.

Rutherfordium was the first super heavy element to be discovered and is located in the transition metals after the actinides. The element was discovered in Dubna, by Geogry Flerov and his team who bombarded plutonium with neon ions. It as first discovered in 1964 but it was not until 1966 that the discovery was confirmed. Rutherforidum has few uses outside of nuclear research. It is a solid metal at room temperature and it has a melting point of 2100°c predicted, the boiling point is 5500°c which is also predicted.
