Covalent Bonds and Electron Sharing

The video explains covalent bonds, where atoms share electrons to achieve stability. It uses examples of fluorine, oxygen, nitrogen, and hydrogen to illustrate single, double, and triple covalent bonds. An analogy with dogs helps clarify electron sharing. The video concludes with a summary of covalent bonding principles.
