Uses of element

Silicon is used in glass, steel production and computer chips. Its use in semi-conductors and computer chips, and computer circuit boards has led to the capital of computer and electronic technology being called Silicon Valley.

THE FOUNDER

Facts about the founder

Berzelius was a Swedish Chemist who lived from 1779-1848. He is considered one of the founders of modern chemistry. He discovered silicon in 1824 by melting potassium chips in a silica beaker and washing away the residual by-products. In addition to silicon, he discovered selenium, thorium, and cerium.
