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.
