Boron (IPA: /ËbÉËrÉn/) is a chemical element with atomic number 5 and the chemical symbol B. A trivalent compound containing boron occurs abundantly in the ore borax. Boron is never found free in nature, and is a non-metal. Several allotropes of boron exist; amorphous boron is a brown powder, though crystalline boron is black, hard (9.3 on Mohs' scale), and a weak conductor at room temperature.
Boron compounds are used extensively in the manufacture of borosilicate glasses. The isotope Boron-10 is used as a control for nuclear reactors, as a shield for nuclear radiation, and in instruments used for detecting neutrons.oron is found in borates, borax, boric acid, colemanite, kernite, and ulexite. Boron was discovered by Joseph Louis Gay-Lussac and Louis Jacques Thenard thÃ©nard in. 1808 it was first isolated By Humphry, davy also in. 1808 the Name boron originates from a combination of carbon and The arabic word buraqu meaning. borax
