Meitnerium is a synthetic chemical element; it has symbol Mt and atomic number 109. It is an extremely radioactive synthetic element (an element not found in nature, but can be created in a laboratory).
Meitnerium (109 Mt) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no stable isotopes.The first isotope to be synthesized was 266 Mt in 1982, and this is also the only isotope directly synthesized; all other isotopes are only known as decay products of heavier elements.

The team bombarded a target of bismuth-209 with accelerated nuclei of iron-58 and detected a single atom of the isotope meitnerium-266: [20] 209 83 Bi + 58 26 Fe → 266 109 Mt + n. This work was confirmed three years later at the Joint Institute for Nuclear Research at Dubna (then in the Soviet Union). [20]
