"Watch this video about Simple Structure, Formal Charge and Resonance Part I for Formal Charge, VSEPR Theory, Hybridization in Introduction to Chemistry:  Structures and Solutions. <p>Welcome to week 3! This week includes introduction to the octet rule and expanded octets, formal chargevalence shell electron pair repulsion (VSEPR) theory, sigma and pi bonds, hybridization of the main group elements, and introduction to molecular shapes.</p>\n\n<p>I hope you enjoyed the last two weeks of learning chemistry. Great work on watching videos, posting on the discussion forum and submitting your exercises!</p>"
