Temporary name of the chemical element with atomic number 109. It was first synthesized (one atom!) and identified in 1982 by P. Armbruster, G. M�nzenberg and colleagues at the Gesellshaft f�r Schwerionenforschung at Darmstadt, Germany¹. The name meitnerium (symbol, Mt) was proposed, honoring the physicist Lise Meitner, co-discoverer of nuclear fission, and accepted in 1997 by the IUPAC's Commission on Nomenclature of Inorganic Chemistry.²
