Part of speech: noun

Definitions

1. A metallic element with the atomic number 108 that is highly radioactive and was first synthesized in 1984
2. An element in the periodic table known for its instability and rarity, primarily produced through nuclear reactions
3. A synthetic alkali metal characterized by its short half-life and its position in group 8 of the periodic table

Etymology: Hassium takes its name from Hesse, the German state where the element was first made. The Latin form "Hassia" is the old name for that region, and the suffix "-ium" is the standard ending chemists give to metallic elements, as in "sodium" and "uranium." Together they name an element after a place rather than a person or a property, which is the usual pattern for elements synthesized in a particular laboratory. The element was produced at the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, which lies in Hesse, so the name points to the institute's home region. Its discoverers chose the name in line with that tradition, honouring the land where the work was done rather than a researcher.
