In the latest experiments, scientists at the Lawrence Livermore National Laboratory in California and the Joint Institute for Nuclear Research in Dubna, Russia, bombarded californium with calcium ions to create 118 — the heaviest ever created in such experiments. Scientists said they found their first superheavy element 118 atom in 2002, then found another two atoms in 2005 in a second round of experiments in which they fired 10 to the power of 19 calcium ions at the californium. In the end the atoms of element 118 — also known as ununoctium — lasted 0.9 milliseconds, researchers said.
