  • Element 109 was first synthesized by researchers at Darmstadt, (West) Germany in August of 1983. For 10 days they hurled a beam of iron-58 ions into a bismuth-209 target. They detected the formation of one nucleus of Mt-267 which rapidly "boiled off" a neutron, reverting to Mt-266. This decayed within milliseconds to give (element 107)-262, etc. A committee of the IUPAC suggested the name Meitnerium (Mt) after the German physicist Lise Meitner. Final approval of the name and symbol was given in August 1997.
