Silicon Oxidation Number

The Oxidation state of Silicon (Si) is +2, with atomic number 14. It is the second most abundant element in the earth, exceeded only by oxygen in the atmosphere. It is relatively inactive at ordinary temperatures, when heated it reacts vigorously with the halogens to form halides and with certain metals it forms silicides. Elemental silicon is produced commercially by the reduction of silica (SiO2) with coke in an electric furnace, and the impure product is then refined.

Silicon can be obtained from the oxide by reduction with aluminum. When silicon and carbon are combined at electric furnace temperatures (2,000–2,600 °C [3,600–4,700 °F]), they form silicon carbide. With hydrogen, it forms a series of hydrides, the salines. The three stable isotopes of Si are silicon-28, silicon-29 and silicon-30.
