Three atoms of element 118 (ununoctium, Uuo) were synthesizesed by fusing krypton-86 (8636Kr) with lead-208 (20882Pb) in experiments conducted at at The Lawrence Berkeley National Laboratory, Berkeley, (California, USA), The University of Calfornia (USA), and Oregon State University, Corvallis (USA).
