bohrium
Noun: A synthetic, highly radioactive, metallic chemical element. It is a transuranium element, meaning its atomic number is greater than that of uranium (92), and it is produced artificially in particle accelerators.
The word "bohrium" is used exclusively as a noun to refer to this specific chemical element. It is a proper noun and is typically used in scientific contexts, particularly in chemistry and physics.
Examples: * The discovery of bohrium was confirmed in the 1980s. * Scientists produced a few atoms of bohrium for the experiment. * Bohrium is located in group 7 of the periodic table.
- Chemical Symbol: The chemical symbol for bohrium is Bh.
- Example: The isotope Bh-270 has a half-life of about 61 seconds.
- Systematic element name: Before its official naming, bohrium was referred to by the systematic name unnilseptium (symbol Uns), derived from its atomic number 107.
- Transuranium element: This is the category to which bohrium belongs, along with other elements like neptunium, plutonium, and lawrencium.
There are no true synonyms for the proper name of an element. The only alternative is the former systematic placeholder name: * Unnilseptium (historical/obsolete)
This word has only one specific meaning: it is the name for the chemical element with atomic number 107. It was named in honor of the Danish physicist Niels Bohr.
- a transuranic element
