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.
Mg2+ cation is formed when magnesium (Mg) loses two electrons
its mg2+
Half equations ?? The chemical formula of magnesium oxide is MgO.

Mg2+
Mg, magnesium forms compounds containing Mg2+ ion.
Cu + Mg2 --------> Cu2 + Mg Cu --------------> Cu2 + 2e Mg2 + 2e --------> Mg Cu --------------> Cu2 + 2e (E = +0.35) Mg2 + 2e --------> Mg (E = -2.36V) +0.35 + (-2.36) = -2.01V --------------------------------------… Mg + Cu2 --------> Mg2 + Cu Mg --------------> Mg2 + 2e Cu2 + 2e --------> Cu Mg --------------> Mg2 + 2e (E = +2.36V) Cu2 + 2e --------> Mg (E = -0.35V) +2.36 + (-0.35) = +2.01V
its mg2+
what is the difference between mg and mgl
2H3O+ + Mg → Mg2+ +H2 + 2H2O
The difference is 2.5 mg
Ni2+(aq) + 2e- Ni(s) and Mg(s) Mg2+(aq) + 2e-
Mg2+
