What will I learn?
This course provides a quick, hands-on method for creating precise Lewis structures, calculating formal charges, and assessing resonance forms. You'll work with actual molecules such as CO2, NO3-, SO2, ClF3, and NH3, link 2D diagrams to 3D geometries via VSEPR theory, manage ions and special cases, sidestep typical pitfalls, and end with a foolproof checklist for producing clear, accurate, professional diagrams consistently.
