Common Mistakes When Using “meitnerium”
- Misspelling as 'meitnerum', 'meitneriam', or 'mietnerium'.
- Incorrect pronunciation with stress on the first syllable (/ˈmaɪtnəriəm/). Correct stress is on the second syllable.
- Using it as a common noun (e.g., 'a meitnerium' instead of 'the element meitnerium' or just 'meitnerium').
FAQ
Frequently Asked Questions
Meitnerium is a synthetic chemical element with the symbol Mt and atomic number 109. It is radioactive and does not occur naturally.
It is produced artificially by bombarding lighter atomic nuclei, like bismuth-209, with accelerated ions, such as iron-58, in a particle accelerator.
Like all highly radioactive elements, it would be hazardous, but its extreme rarity and short half-life (lasting milliseconds to seconds) mean it poses no environmental or practical risk.
It was named in honour of the Austrian-Swedish physicist Lise Meitner, a co-discoverer of nuclear fission.
A synthetic, highly radioactive chemical element with atomic number 109.
Meitnerium is usually scientific, technical in register.
Meitnerium: in British English it is pronounced /maɪtˈnɪə.ri.əm/, and in American English it is pronounced /maɪtˈnɪr.i.əm/. Tap the audio buttons above to hear it.
