Data Program, but require an annual fee to access. According to the lewis structure of SiCl4, the central atom(silicon) doesnt contain any lone pair on it.
Silicon tetrachloride (SiCl4) is an inorganic compound that is used in commercial applications to produce highly pure silicon or silica. The molecular geometry of SiCl4 is tetrahedral and its electron geometry is also tetrahedral because as per VSEPR theory, molecular shape considers only bond pairs or atoms while electron geometry considers bonded atoms as well as lone pairs present on the central atom.
If you see the molecular geometry of SiCl4, all four chlorine atoms are equally spaced around the silicon atom in a tetrahedron corner.
Therefore, the above lewis dot structure of SiCl4 is the best and most stable due to having a formal charge on each atom zero. IUPAC Standard InChI: InChI=1S/Cl4Si/c1-5 (2,3)4.

Adobe Bridge CS6 (Windows) As you see in the above structure, we put the 6 valence electron as dots around each chlorine atom, and these chlorine atoms already sharing the two electrons with the help of a single bond. The market is expected to reach a value of over USD 2.846 million by the end of the forecast period. 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 derivatives are the starting point for the production of aerogels products with high market potential, strongly developing in the construction, automotive and pharmaceutical industries. So the above lewis dot structure of SiCl4 can also be represented as shown below.
