Tin(IV) Phosphate and Polyatomic Ions

The video tutorial explains how to write the formula for Tin(IV) Phosphate. It begins by identifying the transition metal tin and the polyatomic ion phosphate. The video details the charges of tin (4+) and phosphate (3-) and demonstrates the crisscross method to balance these charges, resulting in the formula Sn3(PO4)4. The tutorial concludes by verifying the formula to ensure the net charge is zero.
