Ionic Compounds and Electron Configuration

This video covers section 7.1 about ions, focusing on determining valence electrons in representative elements and understanding the formation of cations and anions. It explains how to use group numbers to find valence electrons, introduces electron dot structures, and discusses the octet rule. The video also covers the naming conventions for cations and anions, providing examples for clarity.
