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.
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 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.
Mg2+
it is +2. the ion is represented as Mg2+.
The chemical formula of carbonate anion is (CO3)2-.The chemical formula of magnesium cation is Mg2+.
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,
Mg2+
The charge on a magnesium ion with 10 electrons (Mg2+) is +2.
It depends if it the ion of magnesium, if it is the ion, then it is positive. If not, then it is neutral.
Mg(OH)2
Because the element magnesium is in the Group II category, it is has two electrons in its outer shell, donating them to leave it with a 2+ charge. Therefore, when it is in the ionized form, it is Mg2+
Mg2+ It loses two electrons when it's ionized
