Meitnerium is a synthetic element that was first synthesized in 1982 by a German research team. It is named after Lise Meitner, a pioneering physicist who made significant contributions to the discovery of nuclear fission. Meitnerium is a highly radioactive element with an atomic number of 109, placing it in the transactinide series of elements. It is incredibly rare, and only a few atoms of meitnerium have ever been produced. Because of its radioactive nature, meitnerium has no known biological role and is not safe for humans to handle or be near. Research on meitnerium primarily focuses on understanding its physical and chemical properties to expand our understanding of the chemical behavior of heavy elements.
