Meitnerium is a metal in Group VIIIB and the 7th period. It is a synthetic element; none occurs naturally on earth.

The element was discovered by physicists at the Heavy Ion Research Laboratory, Darmstadt, Germany, in August, 1992. It was named for Lise Meitner, an Austrian-Swedish physicist and mathematician.

Mt is synthetic, just as are are all other elements beyond U. It was made by bombarding 209Bi with accelerated nuclei 58Fe.

Little is known about the chemistry of Meitnerium. It is expected to have properties similar to Iridium.
