U.S. and Russian team discover element 118

Researchers from Lawrence Livermore National Laboratory working with scientists from Russia's Joint Institute for Nuclear Research (Dubna) say they have discovered element 118.

Three atoms of the super-heavy element, which has yet to be named, were created by bombarding a target made of californium with high-velocity calcium ions. It quickly transformed into element 116, then 114, through alpha particle decay. This is the fifth "new" element discovered by the Livermore-Dubna team (113, 114, 115, 116, and 118). Element 118 is expected to be a noble gas and lie right below radon on the periodic chart of elements.
