In 1982, a German research team led by Peter Armbruster and Gottfried Münzenberg at the Institute for Heavy Ion Research created a new element. While bombarding bismuth-209 atoms with iron-58 ions, they detected a single atom of what is now called meitnerium. Its atomic number is 109. The artificially-produced, radioactive element is named for Lise Meitner, the Austrian-Swedish physicist and mathematician who helped discover nuclear fission. When was the name “meitnerium” officially adopted? Discuss
