Understanding Vanadium and Carbonate Compounds

The video tutorial explains how to name the compound VCO32. It begins by identifying the components: vanadium, a transition metal, and CO3, a polyatomic ion known as carbonate. The tutorial then demonstrates how to name the compound as vanadium carbonate. Since vanadium is a transition metal, the oxidation number must be determined. The video calculates the oxidation number to be 4+, leading to the final name: vanadium (IV) carbonate. The tutorial concludes with a note on writing formulas from names.
