How silicon is made - material, making, history, used

When silicon is heated it reacts with the halogens (fluorine, chlorine, bromine, and iodine) to form halides. It reacts with certain metals to form silicides and when heated in an electric furnace with carbon, a wear resistant ceramic called silicon carbide is produced. Hydrofluoric acid is the only acid that affects silicon.

oxidation nuer of si (silicon)? | Yahoo Answers

2010-4-13 · Best Answer: The most common oxidation states of silicon are +2 (e.g. silicon carbide, SiC) and +4 (e.g. silicon dioxide, SiO2). The reason the most common oxidation states of silicon are positive is because most elements that silicon forms compounds with are of greater electronegativity than silicon (e.g. O as in SiO2, or F as in SiF4.
