The video tutorial explains how to draw the Lewis structure for lithium carbonate (Li2CO3). It begins by identifying lithium as a metal and carbonate as a polyatomic ion, forming an ionic compound. The tutorial details how lithium transfers its valence electrons to carbonate, resulting in a positive charge for lithium and a negative charge for carbonate. This electron transfer leads to the formation of ionic bonds. The video also explains the concept of a formula unit and how these units form a crystal structure in ionic compounds.
