The video tutorial explains how to write the formula for barium nitrate. It begins by identifying barium on the periodic table and recognizing nitrate as a polyatomic ion. The tutorial then discusses the ionic charges of barium and nitrate, emphasizing the need for a net charge of zero. The crisscross method is used to balance these charges, resulting in the correct formula for barium nitrate. The video concludes with a verification of the formula.
