Phosphate Ions and Vanadium Compounds

The video tutorial explains how to name the compound V3PO4, known as Vanadium 5 Phosphate. It begins by identifying vanadium as a transition metal and PO4 as a polyatomic phosphate ion. The tutorial then details how to determine the oxidation number of vanadium using Roman numerals, resulting in the name Vanadium 5 Phosphate. The video concludes with a reference to additional resources for writing chemical formulas.
