The formula and charge for the carbonate ion is CO32- and the formula and charge of the magnesium ion is Mg2+. Together they make magnesium carbonate, MgCO3.
The chemical formula of carbonate anion is (CO3)2-.The chemical formula of magnesium cation is Mg2+.
The formula and charge of the nitrate ion is NO3-, and the formula and charge of the magnesium ion is Mg2+. Together they make magnesium nitrate, Mg(NO3)2.
The ionic charge on "Mg2", presumably meaning the cation whose formula is Mg+2, is +2. In the unlikely event that "Mg2" means a diatomic molecule of elemental magnesium, the ionic charge would be 0,
hydrogen carbonate (aka bicarbonate) is the polyatomic ion you're looking for. Mg(HCO3)2 Mg2+ (HCO3)-
AnswerCO32-, a negative charge of two. Formula of carbonate ion is:CO32-CO3 2-
The chemical formula of carbonate anion is (CO3)2-.The chemical formula of magnesium cation is Mg2+.
Formula for magnesium hydrogen carbonate is Mg(HCO3)2.

The formula and charge for the hydroxide ion is OH-, and the formula and charge for the magnesium ion is Mg2+. Together they make magnesium hydroxide, Mg(OH)2.
CaCo3
Copper(II) Carbonate (or Cupric Carbonate) is made up of Copper ions, and Carbonate ions. The coppers have a +2 charge, and carbonate has a -2 charge. The formula is Cu(II)CO3
AnswerCO32-, a negative charge of two. Formula of carbonate ion is:CO32-CO3 2-
CaCO3
It is Lead Carbonate, but to be more specific, it is Lead (II) Carbonate. Lead can have a charge of +2 or +4. A carbonate ion has a charge or -2. So, in order for the chemical formula to be PbCO3 the lead ion must have a charge of +2, hence the (II) between the lead and carbonate.
The answer, barium II carbonate is wrong for the formula BaCO3 because barium has only one possible charge.
