Lewis Diagram Course
Build confidence in Lewis diagrams through this chemistry course. Hone skills in counting valence electrons, analysing resonance, determining VSEPR shapes, and computing formal charges to accurately draw, interpret, and discuss molecular structures for research or industry applications. Practice with common species like CO2, NO3-, SO2, ClF3, and NH3 while mastering exceptions and avoiding errors.

What will I learn?
Gain a quick, hands-on method for sketching precise Lewis structures, calculating formal charges, and assessing resonance forms. Practice on actual molecules such as CO2, NO3-, SO2, ClF3, and NH3; link 2D diagrams to 3D geometries via VSEPR theory; manage ions and odd cases; dodge typical pitfalls; and end with a foolproof checklist for spot-on, professional diagrams every time.
