History

On February 1, 2004, ununtrium and ununpentium were reported by a team composed of Russian scientists at Dubna (Joint Institute for Nuclear Research), and American scientists at the Lawrence Livermore National Laboratory. Their discovery of the element still awaits confirmation. [1]

Ununtrium is a temporary IUPAC systematic element name. There is an ongoing element naming controversy over what this element should be called.
