Silicon \Sil"i*con\, n. [See Silica.] (Chem.)
A nonmetalic element analogous to carbon. It always occurs
combined in nature, and is artificially obtained in the free
state, usually as a dark brown amorphous powder, or as a dark
crystalline substance with a meetallic luster. Its oxide is
silica, or common quartz, and in this form, or as silicates,
it is, next to oxygen, the most abundant element of the
earth's crust. Silicon is characteristically the element of
the mineral kingdom, as carbon is of the organic world.
Symbol Si. Atomic weight 28. Called also silicium.

Metalloid element belonging to group 14 of the periodic table. It is the
second most abundant element in the Earth's crust, making up 25.7% of it
by weight. Chemically less reactive than carbon. First identified by
Lavoisier in 1787 and first isolated in 1823 by Berzelius.
