The video tutorial explains how to write the chemical formula for Cobalt 2 Nitride. It begins by identifying the element symbols for Cobalt and Nitrogen, noting that Cobalt is a transition metal with a 2+ charge and Nitrogen has a 3- charge. The tutorial then demonstrates the crisscross method to balance these charges, resulting in the formula CO3 N2. Finally, the video verifies the formula by ensuring the net charge is zero, confirming the correctness of the formula.
