History

Nihonium was first reported to have been created in 2003 by the Joint Institute for Nuclear Research in Dubna, Russia, and in 2004 by a team of Japanese scientists at RIKEN. In 2015 the International Union of Pure and Applied Chemistry recognised the element and assigned the priority of discovery to RIKEN.
