This is a very stressful and difficult time for all of us. I am going to leave lecture 30 and 31 quizzes open until Sunday at 11:59pm to give you a bit of extra time.

In this lecture you will learn more about resonance and how to calculate formal charges in a Lewis structure. Formal charges are a way of analyzing how electrons are assigned to atoms in a Lewis structure. The best Lewis structures minimize formal charges and place negative formal charges on the most electronegative atom(s).
