Meitnerium: the essentials

 Brief description: element 109, meitnerium, is a synthetic element that is not present in the environment at all. There is no dispute concerning the name meitnerium for element 109.

The interested reader should consult the on-line version of The Wonderful World of Atoms and Nuclei for a fascinating insight into research on "super-heavy" atoms.

Isolation

Isolation: only a few atoms of element 109, meitnerium, have ever been made. The first atoms were made through a nuclear reaction involving fusion of an isotope of bismuth, 209Bi, with one of iron, 58Fe.

209Bi + 58Fe → 266Mt + 1n

Isolation of an observable quantity of meitnerium has never been achieved, and may well never be. This is because meitnerium decays very rapidly through the emission of α-particles.
