MEITNERIUM
Meitnerium is a synthetic chemical element with atomic number 109, denoted by the Symbol" Mt". This element, which is radioactive, is an element that can only be produced in the laboratory, which is not found in nature. It takes its name from Austrian physicist Lise Meitner. It was first synthesized on 29 August 1982 by a team working at the Darmstadt Institute for Heavy Ion Research under the direction of Peter Armbruster and Gottfried Münzenberg. The team bombarded a target consisting of bismuth-209 with accelerated iron-58 cores. The synthesis of the new element showed that it is possible to create new heavy elements by nuclear fusion techniques. No chemical experiments have yet been conducted to confirm whether the element found in period 7 and group 9 acts as a heavier homologue of Iridium in Group 9, as the seventh member of the 6D series transition metals. Lighter homologs of meitnerium have been calculated to have similar properties to cobalt, rhodium, and Iridium.
So far, only small amounts of meitnerium have been obtained. Therefore, it is currently only used in scientific research. It is also thought to have similar properties to cobalt, rhodium, and iridium based on its position in the periodic table.
