NO!!!!
Mg( magnesium is an ATOM.
However, Mg^(2+) is an ION ( cation).
NB When a neutrally charged an element is an ATOM. When its gains or loses electrons it becomes an ION.
The anions, of which there are two in each formula unit, are chloride ions with the formula Cl-1.
MgOH2 the anion is OH-
The Mg atom has more electron than the Mg+2 ion.
Chloride ions have a charge of 1-. Since the charge on an Mg ion is 2+, the formula unit of Magnesium Chloride is MgCl2. There are 2 chloride ions for each Mg ion.

It depends if it the ion of magnesium, if it is the ion, then it is positive. If not, then it is neutral.
YES!!! Mg(OH)2 = Mg^(2+) + 2(OH)^- The magnesium ion and ther hyroxide ions , combine ionically. However, within the hydroxide ion the oxygen and hydrogen combine covalently.
Mg2+
The Mg atom has more electron than the Mg+2 ion.
The ion has a smaller diameter.
+2
Mg++
2H3O+ + Mg → Mg2+ +H2 + 2H2O

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.
Mg2+
Chloride ions have a charge of 1-. Since the charge on an Mg ion is 2+, the formula unit of Magnesium Chloride is MgCl2. There are 2 chloride ions for each Mg ion.
