Use what you know about valence structure to predict how chlorine will bond with Silicon. E.C. What shape do you predict this molecule will take?
Chlorine has 7 valence electrons, while silicon has 4 valence electrons. To complete their octets, silicon needs 4 more electrons, and chlorine needs only 1 more electron.
Based on valence structure, chlorine will bond with silicon through a single covalent bond, as chlorine will donate one of its electrons to form a bond with silicon. In this scenario, a chloride ion (Cl-) would form and silicon would become positively charged.
Therefore, the resulting molecule is silicon chloride (SiCl), where the chlorine atom donates one electron to form a single bond with the silicon atom.
As for the shape of the molecule, silicon tetrachloride (SiCl4), formed by four chlorine atoms bonding with silicon, is a tetrahedral molecule. Silicon is the central atom, with the four chlorine atoms positioned around it, forming four covalent bonds.
