Lithium Chloride and Ionic Compounds

The video tutorial explains how to determine the chemical formula for lithium chloride by examining the periodic table. It identifies lithium as a metal and chlorine as a non-metal, forming an ionic compound. The tutorial demonstrates balancing the charges of lithium (+1) and chlorine (-1) to ensure the net charge is zero, resulting in the formula LiCl. The video concludes with a brief cleanup of the formula and a thank you from Dr. B.
