In this video lecture, Chemguy instructs on formal charge calculation and resonance.

Some definitions discussed in this lesson:
- Format Change = Free atom valence - Assigned valence.
- All formal charges in molecule must total the overall charge.
- The more electronegative element, like oxygen, must have the lower formal charge.

In this course, Rob Lederer (Chemguy) covers the entire Advanced Placement Chemistry curriculum for Grade 12 students enrolled in a Chemistry AP course. Topics included in these video lectures are: Thermodynamics, Bonding, Kinetics, Solutions, Stoichiometry and many more.

This course is also complemented by Chemguy's video lecture series: Senior Chemistry with Chemguy. It covers topics which this course does not, such as Redox Chemistry and Acids and Bases.

Perfect for high school students and even college students enrolled in an introductory chemistry course, Chemguy provides us with great and easy-to-follow lessons on the AP Chemistry curriculum, all made possible thanks to his great enthusiasm, passion for the subject and sense of humor.
