What are the cations and anions for V2 (CO3) 3

In chemistry, the nomenclature convention would be placing the cation first, followed by the anion. A cation is the positively charged ion, while an anion is the negatively charged ion. When these ions combine, their charges are 'cross-multiplied' and transformed to subscripts of the compound. Therefore, for the compound V ₂ (CO ₃) ₃, the cation is V³⁺ and the anion is CO₃²⁻.
