Silicon single crystal 14Si28.086
Discovered in 1824 by J.J. Berzelius at Stockholm, Sweden.
[Latin: silicium = hard stone]
Description: Black amorphous silicon is obtained by the reduction of sand (SiO2) with carbon. Ultrapure crystals if silicon have a blue-grey metallic sheen. Bulk silicon is unreactive towards oxygen, water and acids (exept HF), but dissolves in hot alkalis. Silicon is used in semiconductors, alloys and polymers.
