Meitnerium: the essentials

Meitnerium atoms have 109 electrons and the shell structure is 2.8.18.32.32.15.2. The ground state electronic configuration of neutral meitnerium is [Rn].5f14.6d7.7s2 (a guess based upon that of iridium) and the term symbol of meitnerium is 4F9/2 (a guess based upon guessed electronic structure).

Meitnerium: 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.

Meitnerium: 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.
