Everyday Connection

Meitnerium has no everyday connection, used only in research.

In Pop Culture

Meitnerium�s naming corrected a historical injustice to physicist Lise Meitner.

It is named in honor of Lise Meitner, the Austrian-Swedish physicist who was a pioneer in nuclear physics and a co-discoverer of nuclear fission.

2

The naming of the element after Meitner was seen as a long-overdue honor for a brilliant scientist who was overlooked for the Nobel Prize for the discovery of fission.

3

It was created by bombarding a bismuth-209 target with iron-58 ions. The first synthesis produced only a single atom.

4

It is a member of Group 9 and is expected to be a very dense, solid metal at room temperature.
