Facts
about the Classification of the Element Boron
Boron is classified as a "Metalloid" element and is located in
Groups 13, 14,15, 16 and 17 of the Periodic Table. An element classified
as a Metalloid has properties of both metals and non-metals. Some are
semi-conductors and can carry an electrical charge making them useful in
calculators and computers.
Brief Facts about the
Discovery and History of the Element Boron
Jons Jacob Berzelius identified boron as an element in 1824. It
was isolated by Sir Humphrey Davy, Gay-Lussac and L. J. Thenard
in 1808. Pure boron was produced by the American chemist W.
Weintraub in 1909. Occurrence of the
element Boron in
the Atmosphere
Obtained from kernite, boric acid, colemanite, ulexite and borates
and produced in USA and Turkey. Boric acid is sometimes found in
volcanic spring waters. Common Uses of Boron
Heat resistant alloys
