Meitnerium (pronounced /maɪtˈnɝiəm/), also called eka-iridium, is a chemical element in the periodic table that has the symbol Mt and atomic number 109. It is a synthetic element whose most stable isotope is Mt-276 with a half-life of 720 milliseconds.
Meitnerium was first synthesized on August 29, 1982 by a German research team led by Peter Armbruster and Gottfried Münzenberg at the Institute for Heavy Ion Research (Gesellschaft für Schwerionenforschung) in Darmstadt.
The synthesis of this element demonstrated that nuclear fusion techniques could be used to make new, heavy nuclei.
The name meitnerium was suggested in honor of the Austrian physicist and mathematician Lise Meitner, but there was an element naming controversy as to what the elements from 101 to 109 were to be called; thus IUPAC adopted unnilennium (/ˌjuːn
