The charge on a magnesium ion with 10 electrons (Mg2+) is +2.
The sodium ion will be larger. Because magnesium has one more proton than sodium, its nuclei pull harder on the electrons, reducing the ion's radius. This means that the magnesium ion is smaller.
A Magnesium ion has a charge of 2+.
Mg2+
The chemical symbol for a magnesium atom is Mg. If you see a "2" after it as a subscript, that implies that you are looking at the chemical formula for a molecule that contains two magnesium atoms. But if you see a "2+" written after it as a superscript, that implies that the magnesium is not an atom, but an ion with a relative charge of positive 2. For example, you may see this: Mg2+ + 2 HCO3- --> MgCO3 + CO2 + H2O The "Mg2+" refers to a magnesium ion with a +2 charge.
the symbol for the magnesium ion is Mg2+
It depends if it the ion of magnesium, if it is the ion, then it is positive. If not, then it is neutral.

Mg, magnesium forms compounds containing Mg2+ ion.
MgSO4 due to the combination of a Mg2+ ion and a SO42- ion.
Mg is the symbol for the element magnesium and could be used to represent a neutral atom of magnesium. Mg2- does not occur, but Mg2+ does, and is the symbol of a magnesium ion, which is a magnesium atom that has lost two electrons.
Magnesium, with a +2 charge.
The symbol for magnesium is Mg.
Magnesium once formed an ion the charge is 2+ .
