The ionic charges MUST balance. Since Cr^(3+) does not balance with CO3^(2-) , we must adjust the ions so that the overall charges balance. Hence Cr^(3+) + Cr^(3+) gives '6+' ( 2Cr^(3+) ) Similarly CO3^(2-) + CO3^(2-) + CO3^(2-) gives '6-' ( 3CO3^(2-)). NB THe charges balance at '6+' & '6-' . Hencce we need two moles of the cation and three moles of the anion. Cr3(CO3)2 is the formula for chromium carbonate.
The chemical name for V(CO3)2 is vanadium(III) carbonate.
The ionic compound for aluminum carbonate is Al2(CO3)3. In this compound, aluminum has a charge of +3 and the carbonate ion has a charge of -2, so the formula is derived by combining these ions in a way that balances the charges.
