Answer:
To draw a Lewis structure for a covalent compound, begin by calculating A, the available electrons, and N, the needed electrons.
What is N for silicon tetrachloride, SiCl4?
Explanation:
A covalent compound is formed by the mutual sharing of electrons between two atoms.
According to Lewis octet theory, every atom wants to attain eight electrons around it.
For the given molecule SiCl4
Silicon has four valence electrons.
To attain the nearest inert gas configuration it requires four more electrons.
Each chlorine atom shares an electron and thus silicon attains eight electrons in its valence shell.
The Chlorine atom has seven valence electrons.
To get eight electrons in its valence shell it needs one more electron.
That is shared by the silicon atom.
Thus both Si and Cl attain eight valence electrons by sharing electrons and for the covalent bond.
N value for Si is --- 4.
A the available electrons for Si is ---- 4.
The available electrons for Si 4 and the needed electrons are also 4. A covalent compound is formed by the equal sharing of electrons between two atoms.

According to Lewis octet theory, every atom wants to attain eight electrons in the shell.
For the given molecule [tex]\bold {SiCl_4}[/tex]
- Silicon has four valence electrons and Chlorine has 7 electrons in the valence shell.
- It requires four more electrons to attain the nearest inert gas configuration for silicon and one more electron for chlorine.
- Each chlorine atom shares an electron and thus silicon attains eight electrons in its valence shell.
Thus both Si and Cl attain eight valence electrons by sharing electrons and for the covalent bond.
Therefore, the available electrons for Si 4 and the needed electrons are also 4.
