Meitnerium (atomic number 109, symbol Mt) is a chemical element synthesized by Gottfried Munzenberg and Peter Armbruster at the Darmstadt Institute for Heavy Ion Research in 1982. The team used nuclei of iron-58 to bombard bismuth-209 and detected meitnerium-266. The half-life of this isotope is 0.0038 seconds or 3.8 milliseconds. The most stable isotope of meitnerium is meitnerium-278 and through alpha decay, it decays into bohrium-274. Its half-life is around 11 seconds.
The element was originally known as unnilennium and named after the physicist Lise Meitner. IUPAC adopted the name in 1997.
