Mg2+
The most likely charge for an ion of magnesium (Mg) is 2+. This is because magnesium has two valence electrons, and it is energetically favorable for it to lose these electrons and achieve a stable octet configuration, resulting in a +2 charge.
Mg, magnesium forms compounds containing Mg2+ ion.
Mg-24
Mg2+
All the elements in Group 2A (Mg, Ca, etc.). A charge of 2+ is acquired by these metals in order for a more stable state to be achieved.
Magnesium as an atom has two valance electrons. To complete it's octet, it must lose two electrons. Losing two electrons will make Mg have 12 protons and 10 electrons therefore having a +2 charge.
It depends if it the ion of magnesium, if it is the ion, then it is positive. If not, then it is neutral.
+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.
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.
Mg or the element magnesium has only one possible charge of +2. Just a hint but all elements in group 2 have a charge of +2 ie. Be, Ca, Sr...
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.
Mg, magnesium forms compounds containing Mg2+ ion.
Mg as an element is zero oxygen as an element is likewise zero Mg as an ion +2 Oxgen as an ion -2 MgO compound net zero
Ions have a charge therefore (4) is an Ion.
Mg ^ 2+ :D
Magnesium (Mg)
There is only one ion of magnesium: Mg2+ because it is an 'earth alkali' metal (group 2 in the periodic table).
