- ‘One potential candidate for such a long-living element is hassium, which contains about 180 neutrons.’
- ‘The researchers established that hassium forms a gaseous oxide similar to that of osmium, confirming that hassium, like osmium, is a member of group 8 of the periodic table and should be placed directly under it.’
- ‘They have anywhere from 13 isotopes to one isotope (e.g., hassium and meitnerium).’
- ‘Hassium does not occur in nature, and it has no isotopes that last long enough to allow significant quantities to be accumulated.’
- ‘Element 108 is called hassium, after the German state of Hesse wherein Darmstadt is situated.’
