Ooh I have (rather late) discovered the periodic table. I don't think I will try again to set up an avatar because Meitneriun is somewhat elusive in appearance

meitnerium.

Standard state: presumably a solid at 298 K
Colour: unknown, but probably metallic and silvery white or grey in appearance
Classification: Metallic
Availability:

Element 109, meitnerium, is a synthetic element that is not present in the environment at all.

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 a-particles.


Very appropriate....grey, dilapidated ... I dispute the synthetic ......
