Where is the element meitnerium found?
Darmstadt
Meitnerium was first discovered in 1982 in Darmstadt, in what was then West Germany. A single atom was made by bombarding a target of bismuth with accelerated nuclei of iron, to make the isotope meitnerium-266, which has 157 neutrons in its nucleus, together with the 109 protons which define the element.
Is meitnerium toxic?
Uses of Meitnerium: Meitnerium’s primary use is for scientific research, since only minute amounts of this element have ever been produced. The element plays no biological role and is expected to be toxic due to its inherent radioactivity.
What is meitnerium classification?
Meitnerium is a chemical element with symbol Mt and atomic number 109. Classified as a transition metal, Meitnerium is a solid at room temperature.
What is the use of the element darmstadtium?
A highly radioactive metal, of which only a few atoms have ever been made. At present, it is only used in research. Darmstadtium has no known biological role. A man-made element of which only a few atoms have ever been created.
What are the isotopes of meitnerium?
Eight different isotopes of meitnerium have been reported with atomic masses 266, 268, 270, and 274–278, two of which, meitnerium-268 and meitnerium-270, have known but unconfirmed metastable states. A ninth isotope with atomic mass 282 is unconfirmed.
What is meitnerium atomic mass number?
109
Meitnerium/Atomic number
Is meitnerium a solid liquid or gas?
Meitnerium is a radioactive, synthetic element about which little is known. It is classified as a metal and is a solid at room temperature.
What family does meitnerium belong to?
transuranium group
meitnerium (Mt), an artificially produced element belonging to the transuranium group, atomic number 109. It is predicted to have chemical properties resembling those of iridium. The element is named in honour of Austrian-born physicist Lise Meitner.
What does darmstadtium decay into?
Darmstadtium’s most stable isotope, darmstadtium-281, has a half-life of about 20 seconds. About 15% of the time, it decays into hassium-277 through alpha decay. The remaining 85% of the time, it decays through spontaneous fission.
Is darmstadtium natural or synthetic?

What is meitnerium melting point?
Lithium metal is produced by electrolysis of a fused mixture of lithium and potassium chlorides. The lower melting point of the mixture (400–420 °C, or 750–790 °F) compared with that of pure lithium chloride (610 °C, or 1,130 °F) permits lower-temperature operation of the electrolysis.
Why is meitnerium 109?
Meitnerium is a synthetic chemical element with the 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)….

What are the characteristics of the meitnerium?
Meitnerium assumes a cubic crystal structure,and similar to iridium.
What is meitnerium atomic mass?
Meitnerium should have a high melting point and be very corrosion-resistant. It should be a heavy metal as well and is projected to be the heaviest member of group 9, after iridium , rhodium , and cobalt . The atomic weight of meitnerium is 278, and it is solid at room temperature.
What does meitnerium mean?
Meitnerium is a metallic chemical element classified among the transactinides on the periodic table of elements. Like other transactinide elements, meitnerium is among the heaviest of chemical elements, and it is both extremely unstable and radioactive.
