In this case, carbon is the central atom.
Determine the total number of valence electrons in the molecule.To draw the Lewis structure of CCl4, we follow these steps: Valence electrons of carbon (4) + Valence electrons of chlorine (4 × 7) = 32 Steps to Draw the CCl4 Lewis Structure
Therefore, the total number of valence electrons in CCl4 is: Chlorine, on the other hand, is in group 17 and has seven valence electrons. To draw its Lewis structure, we need to consider the valence electrons of each atom.Ĭarbon is located in group 14 of the periodic table, so it has four valence electrons. Carbon tetrachloride is a chemical compound composed of one carbon atom and four chlorine atoms. Let’s take the example of carbon tetrachloride (CCl4) to understand the concept of Lewis structures. By representing these electrons as dots around the atomic symbol, we can determine the number of covalent bonds an atom can form. Valence electrons are the outermost electrons of an atom that participate in chemical bonding. What is a Lewis Structure?Ī Lewis structure, also known as a Lewis dot structure, is a diagram that shows the valence electrons of atoms in a molecule. It provides a visual representation of the arrangement of atoms and valence electrons in a molecule, helping us understand its molecular geometry and chemical bonding. In chemistry, the Lewis structure is a way to represent the molecular structure of a chemical compound using Lewis dot symbols. Key Takeaways Atom Number of Valence Electrons Carbon 4 Chlorine 7 Understanding the Lewis Structure The Lewis structure of CCl4 is important in understanding its chemical properties and reactions.

This arrangement allows carbon to have a full octet of electrons, making it stable. Each chlorine atom shares one electron with carbon, resulting in a total of eight valence electrons around the carbon atom. In the Lewis structure, carbon is the central atom surrounded by four chlorine atoms. It is a commonly used solvent and was historically used as a fire extinguisher. The Lewis structure of CCl4, also known as carbon tetrachloride, is a representation of how the atoms are arranged in the molecule.
