Lise Meitner and Otto Hahn

Meitnerium is named after Lise Meitner, who discovered nuclear fission. She is shown here in the laboratory with her colleague Otto Hahn.

Discovery of Meitnerium

Meitnerium was first synthesized by research scientists led by Peter Armbruster and Gottfried Münzenber at the Heavy Ion Research Laboratory in Darmstadt, Germany in 1982.

Meitnerium was produced when bismuth-209 was bombarded with accelerated iron-58 nuclei.

The element was named after physicist Lise Meitner.

Appearance and Characteristics

Harmful effects:

Meitnerium is harmful due to its radioactivity.

Characteristics:

Meitnerium is a synthetic, radioactive metal and has only been produced in tiny amounts.

Uses of Actinium

Meitnerium is of scientific research interest only.

Abundance and Isotopes

Abundance earth’s crust: nil

Abundance earth’s crust: nil

Abundance solar system: nil parts per billion by weight, nil parts per trillion by moles

Cost, pure: $ per 100g

Cost, bulk: $ per 100g

Source: Meitnerium is a synthetic radioactive metal, created via nuclear bombardment, and has only been produced in minute amounts. Meitnerium was produced by bombarding 209Bi with 58Fe which produced a single atom of the isotope 266Mt.

Isotopes: Meitnerium has 7 isotopes whose half-lives are known, with mass numbers from 266 to 278. None are stable. The most stable isotope is 278Mt, with a half-life of 8 seconds.
