Definition of the Silicon Element
A non-metallic element occurring extensively in the earth's crust in silica and silicates, having both an amorphous and a crystalline allotrope, and used doped or in combination with other materials in glass, semi-conducting devices, concrete, brick, refractories, pottery, and silicones.

Origin / Meaning of the name Silicon
The name originates from the Latin word 'silex' meaning flint

Classification of the Silicon Element
Silicon 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.

The Discovery of Silicon
Silicon was  was first identified by Antoine Lavoisier in 1787. Re-discovered by Jons Berzelius in 1823

Facts about the History of the Silicon Element
The high-tech region of Silicon Valley, California, is named after this element.

Silicon and the Periodic Table
Check out Silicon on the Periodic Table which arranges each chemical element according to its atomic number, as based on the periodic law, so that chemical elements with similar properties are in the same column. Our Periodic Table is simple to use - just click on the symbol for Silicon for additional information and for an instant comparison of the Atomic Weight, Melting Point, Boiling Point and Mass - G/cc with any other element. An invaluable source of facts and information as a Chemistry reference guide.

Silicon - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day but still all fitting into his concept of  the "Periodic Table" in which Silicon is just one element that can be found.
