 * Discovery:** Meitnerium was first synthesized or made on August 29, 1982 by Peter Armbruster and Gottfried Münzenberg at the Institute for Heavy Ion Research. They bombarded a bismuth-209 with an accelerated nuclei of iron-58 and found the isotope meitnerium-266.


 * Name:** Named in honor of the austrian scientist, Lise Meitner.


 * Uses:** Only a small amount of meitnerium has been made; it has no uses yet.

- Meitnerium's color is unknown, but it would probably look metalic and silvery white or gray. - Has a half-life of 700 milliseconds.
 * Interesting Facts**: - Meitnerium is classified or called as a "Transition Metal" which are located in Groups 3 - 12 of the Periodic Table. This means that Meitnerium is ductile, malleable, and able to conduct electricity and heat.
