Meitnerium is a synthetic element that is not present in the environment. Isolation of an observable quantity of meitnerium has never been achieved, and thus meitnerium has no known uses. The reactivity of meitnerium is unknown, but is assumed to be similar to rhenium and technetium.

Meitnerium was first synthesized in 1982 at the Gesellschaft für Schwerionenforschung a.k.a the Institute for Heavy Ion Research a.k.a. GSI in Darmstadt, Germany. After ten days of bombardiing Bismuth(209) with Iron(58) they produced one single atom unambiguously identified as meitnerium, via
Bismuth(209) + Iron(58) = Meitnerium(266) + 1 neutron

Element 109 was officially named meitnerium in 1997; Named after Lise Meitner, the Austrian physicist
