A step-by-step explanation of how to draw the CS2 Lewis Dot Structure (Carbon disulfide). For the CS2 structure use the periodic table to find the total number of valence electrons for the CS2 molecule. Once we know how many valence electrons there are in CS2 we can distribute them around the central atom with the goal of filling the outer shells of each atom. In the Lewis structure of CS2 structure there are a total of 16 valence electrons. CS2 is also called Carbon disulfide. The Lewis structure for CS2 requires you have double bonds between the Carbon (C) and Sulfur atoms in order to fill the octet of Carbon. ----- Steps to Write Lewis Structure for compounds like CS2 ----- 1. Find the total valence electrons for the CS2 molecule. 2. Put the least electronegative atom in the center. Note: Hydrogen (H) always goes outside. 3. Put two electrons between atoms to form a chemical bond. 4. Complete octets on outside atoms. 5. If central atom does not have an octet, move electrons from outer atoms to form double or triple bonds. ----- Lewis Resources ----- • Lewis Structures Made Simple: https://youtu.be/1ZlnzyHahvo • More practice: https://youtu.be/DQclmBeIKTc • Counting Valence Electrons: https://youtu.be/VBp7mKdcrDk • Calculating Formal Charge: https://youtu.be/vOFAPlq4y_k • Exceptions to the Octet Rule: https://youtu.be/Dkj-SMBLQzM Lewis Structures are important to learn because they help us understand how atoms and electrons are arranged in a molecule, such as Carbon disulfide. This can help us determine the molecular geometry, how the molecule might react with other molecules, and some of the physical properties of the molecule (like boiling point and surface tension).
