In order to draw the lewis structure of SiCl4, first of all you have to find the total number of valence electrons present in the SiCl4 molecule.
So, as per the VSEPR chart, if the central atom of a molecule contains 0 lone pairs and is cornered by four surrounding atoms, then the molecular shape of that molecule is tetrahedral in nature. The development and growing importance of this raw material depends on the integration of the latest production technologies with dynamic investments on a global scale.

Now, you have come to the final step and here you have to check the formal charge on silicon atom (Si) as well as each chlorine atom (Cl). Octet rule is defined as the rule of having eight electrons in the valance shell of the respective valance shell to achieve the electron configuration like their nearest noble gas in periodic table.
These pairs of electrons present between the Silicon (Si) and Chlorine (Cl) atoms form a chemical bond, which bonds the silicon and chlorine atoms with each other in a SiCl4 molecule. In simple words, we have to check whether the central Silicon (Si) atom is having 8 electrons or not.
