Naming and Charges of Tin Phosphate

The video tutorial explains how to name the compound SN3(PO4)2. It begins by identifying the components: tin, a transition metal, and the polyatomic phosphate ion. The tutorial then outlines the steps to name the compound, starting with the metal followed by the polyatomic ion. Since tin is a transition metal, its charge must be specified using Roman numerals. The video demonstrates how to calculate the charge based on the ionic charges of the phosphate ions, leading to the final name: Tin(II) Phosphate.
