How Was Silicon Named?

Chemicool states that silicon was named by Scottish chemist Thomas Thomson in 1831. Swedish chemist Jöns Jakob Berzelius produced a sample of amorphous silicon and purified the substance, naming it silicium, from "silicis," which means "flint." When Thomson named silicon, he retained part of the name given by Berzelius.

Thomson added the "-o" to the end of the element because of its similarity to nonmetals, such as carbon and boron. According to Chemicool, flint, or silicus, was likely the first use of the element silicon dioxide. Henri Deville produced what was known as crystalline silicon in 1854. He achieved this in the process of electrolyzing impure melt parts of sodium chloride in order to produce aluminium silicide.
