Definition

Meitnerium is a chemical element with the symbol Mt and atomic number 109. It is a synthetic element, meaning it has never been found in nature. It was first created in 1982 by a team of scientists at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany.

Meitnerium is a very rare element. Only a few atoms of meitnerium have ever been created, and they have only existed for a very short time. Meitnerium is also very unstable, and it decays very quickly into other elements.

Meitnerium is named after Lise Meitner, an Austrian physicist who was a pioneer in the study of nuclear fission. Meitnerium is a member of the actinide series, which is a group of elements that are all radioactive.
