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 V₂(CO₃)₃, the cation is V³⁺ and the anion is CO₃²⁻.

Explanation:

Cations are the species that hold a positive charge by losing electrons.

For example, [tex]Na^{+}[/tex], [tex]V^{2+}[/tex], [tex]Ca^{+}[/tex] etc are all cations.

Whereas anions are the species that hold a negative charge by gaining electrons.

For example, [tex]Cl^{-}[/tex], [tex]CO^{2-}_{3}[/tex], [tex]S^{2-}[/tex] are all anions.

Therefore, in the compound [tex]V_{2}(CO_{3})_{3}[/tex], vanadium ([tex]V^{3+}[/tex]) is the cation and carbonate ([tex]CO^{2-}_{3}[/tex]) is the anion.
