Definition of meitnerium in English: meitneriumnoun mʌɪtˈnɪərɪəmmītˈnirēəm mass nounThe chemical element of atomic number 109, a very unstable element made by high-energy atomic collisions. （化学元素）鿏（符号： Mt ） Example sentencesExamples - They have anywhere from 13 isotopes to one isotope (e.g., hassium and meitnerium).
- Element 109 is named meitnerium, for Lise Meitner, who was the first to realize that uranium undergoes nuclear fission.
- Less than 10 atoms of meitnerium have ever been made, and it will probably never be isolated in observable quantities.
- None of meitnerium's chemistry has been researched, but it should resemble other elements of group 9, like iridium.
- The German proposal of ‘meitnerium ‘for 109 was allowed to stand, as were the names proposed for elements 101, 102, and 103 - ‘mendelevium, ‘‘nobelium, ‘and ‘lawrencium, ‘respectively.’
Origin1990s: modern Latin, from the name of L. Meitner (see Meitner, Lise).
