An image of Niels Bohr, for whom Bohrium is named.

Facts about Bohrium:

  • Bohrium: Bohrium is a synthetic element so its properties are unknown, but it is expected to behave like Tecnicium (also a synthetic element) and Rhenium.
  • Fun fact about Bohrium: Bohrium is named for physicist Niels Bohr who was a pioneer in atomic theory.  Bohrium is extremely radioactive and the most stable known isotope, 270Bh, only has a half-life of about one minute.
  • Chemical symbol: Bh
  • Atomic number: 107

A crystal structure celebrating Bohrium:

Rhenium (cyan sphere) is surrounded by four oxygen atoms (red spheres) in what is known as the perrhenate anion. Here it sits inside a cage-like molecule known as a cucurbituril.

Facts about this structure:

  • Formula: C64 H96 N16 O8,C16 H36 N +,1.75(C H4 O),O4 Re -
  • Structure name: tetra-n-butylammonium cycloocta(1-methylene-(octahydro-2H-benzimidazol-2-one-3-yl)) oxido-trioxo-rhenium(vii) methanol solvate
  • Fun fact about the structure: The large cage-like molecule in this structure was used to selectively capture smaller ionic molecules like perrhenate. Perhaps someday a molecule like this will capture perbohrate!
  • CSD refcode: ECAFAS (What's this?)

More info:

Element 107 is named for Niels Bohr, who won the Nobel Prize in Physics for his contributions to atomic theory and quantum physics. Bohrium belongs in Group 7 of the Periodic Table and is expected to behave like other members of that group.
