History

Nihonium was identified in 2003 as an alpha decay product of element 115, moscovium by a team composed of Russian scientists at Joint Institute for Nuclear Research, Dubna and American scientists at the Lawrence Livermore National Laboratory. The Dubna-Livermore collaboration has strengthened their claim for the discovery of nihonium by conducting chemical experiments on the final decay product 268Db. The name comes from the common Japanese name for Japan
