Listen "Topic: Formal Charge"
Episode Synopsis
This episode explains formal charge, a tool for evaluating Lewis structures. It defines formal charge with the formula FC = V - N - B/2 and outline key rules for its use, such as minimizing charges and placing negative charges on more electronegative atoms. It shows how formal charge helps choose the best structure for molecules like carbon monoxide and justifies expanded octets. The episode stresses that formal charge provides a systematic way to determine the most realistic molecular structure.
