Ammonium and Nitride Compounds

The video tutorial explains how to write the formula for ammonium nitride. It begins by identifying ammonium as a polyatomic ion with a positive charge and nitride as nitrogen with a three-minus charge. The tutorial then discusses the need to balance these charges to form an ionic compound, resulting in the formula (NH4)3N. The video concludes with a demonstration of writing the formula and ensuring a net charge of zero.
