Lewis Structures and Valence Electrons

This video tutorial explains how to determine the number of valence electrons in carbon monoxide (CO). It begins by clarifying the difference between CO and cobalt, then uses the periodic table to identify the valence electrons for carbon and oxygen. The tutorial calculates the total valence electrons for CO and demonstrates how to draw its Lewis structure, ensuring each atom achieves an octet. Links for further assistance are provided.
