Rutherfordium General

Name:Rutherfordium Symbol:Rf
Type:Transition Metal Atomic weight:261
Density @ 293 K:g/cm3 Atomic volume:cm3/mol

Rutherfordium was first synthesized in 1964 when scientists at Dubna, Russia bombarded plutonium with accelerated neon ions. The element is named after physicist and chemist Lord Ernest Rutherford, who is known as the 'father' of nuclear physics.
