===Meitnerium===
Meitnerium was [[discovery of the chemical elements|first synthesized]] on August 29, 1982, by a German research team led by [[Peter Armbruster]] and [[Gottfried Münzenberg]] at the [[Gesellschaft für Schwerionenforschung|Institute for Heavy Ion Research]] (Gesellschaft für Schwerionenforschung) in [[Darmstadt]].<ref name="82Mu01">{{cite journal|title=Observation of one correlated α-decay in the reaction <sup>58</sup>Fe on <sup>209</sup>Bi→<sup>267</sup>109|doi=10.1007/BF01420157|year=1982|journal=Zeitschrift für Physik A|volume=309|issue=1|pages=89|last1=Münzenberg|first1=G.|last2=Armbruster|first2=P.|last3=Heßberger|first3=F.
