Ionic Compounds and Polyatomic Ions

The video tutorial explains how to write the formula for lithium chlorite. It begins by identifying lithium as a metal and chlorite as a polyatomic ion, which is not found on the periodic table. The tutorial emphasizes the importance of balancing ionic charges, with lithium having a 1+ charge and chlorite having a 1- charge, resulting in a net charge of zero. The final formula for lithium chlorite is presented as Li2. The video concludes with a brief closing statement.
