Electron Configuration and Structural Formulas of SiCl4 and SO3

The molecule SiCl4 is composed of one silicon atom (Si) and four chlorine atoms (Cl). The electron configuration of silicon is 1s^2 2s^2 2p^6 3s^2 3p^2. Each chlorine atom has an electron configuration of 1s^2 2s^2 2p^6 3s^2 3p^5.

To determine the structural formula of SiCl4, we need to consider the valence electrons of each atom. Silicon has four valence electrons (2 in the 3s orbital and 2 in the 3p orbital), while chlorine has seven valence electrons (2 in the 3s orbital and 5 in the 3p orbital).

Silicon can share its four valence electrons with four chlorine atoms, forming covalent bonds. Each chlorine atom contributes one electron to the bond, resulting in a total of four shared pairs of electrons. The structural formula of SiCl4 is therefore:

SiCl4 ``` Cl | Cl-Si-Cl | Cl ```

The molecule SO3 is composed of one sulfur atom (S) and three oxygen atoms (O). The electron configuration of sulfur is 1s^2 2s^2 2p^6 3s^2 3p^4. Each oxygen atom has an electron configuration of 1s^2 2s^2 2p^4.

To determine the structural formula of SO3, we need to consider the valence electrons of each atom. Sulfur has six valence electrons (2 in the 3s orbital and 4 in the 3p orbital), while oxygen has six valence electrons (2 in the 2s orbital and 4 in the 2p orbital).

Sulfur can share its six valence electrons with three oxygen atoms, forming covalent bonds. Each oxygen atom contributes two electrons to the bond, resulting in a total of six shared pairs of electrons. The structural formula of SO3 is therefore:

SO3 ``` O // O=S=O \\ O ```
