Discovery of Silicon

In 1787, Antoine Lavoisier suspected silica might be an oxide of a fundamental chemical element. Still, the chemical affinity of Silicon for oxygen was high enough that he had no means to reduce the oxide and isolate the part. After an attempt to isolate Silicon in 1808, Sir Humphry Davy proposed the name "silicium" for Silicon, from the Latin silex, silicic for flint. He added the "-mum" ending because he believed it to be metal. Most other languages use transliterated forms of Davy's name, sometimes adapted to local phonology (e.g. German Silizium, Turkish cilium, Catalan silica, Armenian Սիլիցիում or Silitzioum). A few others use a calque of the Latin root instead (e.g. Russian кремний, from кремень "flint"; Greek πυρίτιο from πυρ "fire"; Finnish PII from piikivi "flint", Czech křemík from křemen "quartz", "flint"). Gay-Lussac and Thénard are thought to have prepared impure amorphous Silicon in 1811 by heating recently isolated potassium metal with silicon tetrafluoride.  He retained part of Davy's name but added "-on" because he believed Silicon was a nonmetal similar to boron and carbon.  The same year, Berzelius became the first to prepare silicon tetrachloride; silicon tetrafluoride was already designed in 1771 by Carl Wilhelm Scheele by dissolving silica in hydrofluoric acid. In 1823 for the first time, Jacob Berzelius discovered silicon tetrachloride (SiCl4). In 1846 Von Ebelman he had synthesized Tetraethyl orthosilicate (Si(OC2H5)4).
