+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.
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 symbol for a magnesium ion is Mg^2+. The superscript 2+ indicates that the magnesium ion has a positive charge of 2.
The chemical formula of carbonate anion is (CO3)2-.The chemical formula of magnesium cation is Mg2+.
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...
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.
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.
A Mg atom has an equal number of protons and electrons, resulting in a neutral charge, while a Mg^2+ ion has lost two electrons, giving it a positive charge. This difference in electron configuration affects the reactivity and chemical properties of each.
The overall charge for MgF2 is neutral. Magnesium (Mg) has a +2 charge, while fluoride (F) has a -1 charge. Therefore, to balance the charges, it takes 1 Mg2+ ion and 2 F- ions to form MgF2, resulting in a neutral compound.
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.
Magnesium, with a +2 charge.
