Formal charge arguments work very well for organic compounds when drawing the best Lewis structure. One single bond contains two valence electrons, hence, we used a total of (4 single bonds 2) = 8 valence electrons from 32 available valence electrons for drawing the SiCl4 lewis structure. The molecular geometry of SiCl4 is tetrahedral as all four outer atoms(chlorine) are pushed away in all directions from the central atoms(silicon) because of repelling force occurs in electron pairs around the central atom. if(dataLayer){ More info about absorbents, including situations to watch out for Special Warning from DuPont: Tychem and Tyvek fabrics should not be Anonymous, R., SiCl4 Lewis structure comprises one silicon (Si) atom and four chlorine (Cl) atoms. We will contact you within 2 working days.Thank you for contacting us.Thank you for your query. So, in the case of SiCl4, from silicon and chlorine, silicon(1.8) is less electronegative than chlorine(3.16), as electronegativity increases from left to right across a period in the periodic table. This grade should be free of hydrogen containing impurities like trichlorosilane. Silicon has four valence electrons and chlorine has seven valence electrons.
