  boron
  Symbol: B
  Atomic number: 5
  Atomic weight: 10.811
  An element of group 13 of the periodic table. There are two allotropes,
  amorphous boron is a brown power, but metallic boron is black. The
  metallic form is hard (9.3 on Mohs' scale) and a bad conductor in room
  temperatures. It is never found free in nature. Boron-10 is used in
  nuclear reactor control rods and shields. It was discovered in 1808 by Sir
  Humphry Davy and by J.L. Gay-Lussac and L.J. Thenard.

  Boron \Bo"ron\ (b[=o]"r[o^]n), n. [See Borax.] (Chem.)
     A nonmetallic element occurring abundantly in borax. It is
     reduced with difficulty to the free state, when it can be
     obtained in several different forms; viz., as a substance of
     a deep olive color, in a semimetallic form, and in colorless
     quadratic crystals similar to the diamond in hardness and
     other properties. It occurs in nature also in boracite,
     datolite, tourmaline, and some other minerals. Atomic number
     5. Atomic weight 10.81. Symbol B.
