Facts about the
Definition of the Element Silicon
The Element Silicon is defined as...
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.
Interesting Facts
about the Origin and Meaning of the element name Silicon
What are the origins of the word Silicon ?
The name originates from the Latin word 'silex' meaning flint or
hard stone. The high-tech region of Silicon Valley, California, is
named after this element.
Facts about the
Classification of the Element Silicon
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.

Facts and Info about
the element Argon - 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
which includes the Silicon element. The famous Russian Scientist,
Dimitri Mendeleev, perceived the correct classification method of
"the periodic table" for the 65 elements which were known in his
time. Silicon was was first identified by Antoine Lavoisier in
1787. Re-discovered by Jons Berzelius in 1823. The Standardised Periodic Table 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.
