polycrystalline chunks of β-rhombohedral boron

Middle Persian *bōragbor.

English boron

From the stem of borax (boro-) + -on (based on carbon). Coined by British chemist Humphry Davy as a modification of his earlier word boracium.

boron (usually uncountable, plural borons)

  1. The chemical element (symbol B) with an atomic number of 5, which is a metalloid found in its pure form as a dark amorphous powder.

      The B6-type octahedral borons are each bonded to five other boron atoms; four are part of the same octahedron, and one is external to this octahedron.
    • 2018 November 20, Wayne Drash, “Consumer group warns of ‘dangerous’ slime products and other hazardous toys”, in CNN‎[1]:
      PIRG noted the European Union has a limit of 300 ppm for boron and that there should be a “full-fledged investigation to determine if limits should be established” in the US.
  2. A single atom of this element.
