Silicon tetrafluoride or tetrafluorosilane is the chemical compound with the formula SiF₄. This colorless compound is notable for having a narrow liquid range: its boiling point is only 4 °C above its melting point. It was first synthesized by John Davy in 1812. It is a tetrahedral molecule.

Is Silicon a tetrafluoride?

Silicon Tetrafluoride is a colorless gas with a strong odor. It is used to seal water out of oil wells and in the production of Silicon and Fluosilicic Acid. * Silicon Tetrafluoride is on the Hazardous Substance List because it is cited by DOT and NFPA.

What is the charge of Si in SiF4?

Answer: +4

Fluorine is more electronegative, so each fluorine atom receives its preferred negative oxidation state of -1. There is no net charge on this molecule. Therefore, to balance, the silicon atom must receive a positive oxidation state of +4.
