    \[mg \rightarrow mg ^{2+} + 2 e\]

    well, that i get, im just not sure how to do so. For example: Ba -> Ba^(2+) + _______ ??? How would i get rid of the two? is that what yhou mean im supposed to do? sorry, chemistry is very confusing to me...

    ah.. how to explain it. if 2e = debt (-2) so, we must pay it by +2. just like that. but, we must write it on the right-top the element (Mg)

    well, magnesium has 12 protons - by definition, to be a neutral atom the positive charges of the protons is canceled out by negatively charged electrons , (-)elections and (+)protons have a charge that is equal in magnitude and opposite in sign, \[ _{12}\text{Mg}^0 \longrightarrow \_\_ + 2e^- \] \[ _{12}\text{Mg}^0 -2e^- = \_\_ \] taking away electrons from magnesium will effect the overall charge \(0-(-2)=2\) the nucleus of the atom will remain the same

    yup, u must pay it by ...... electron(s). to make it neutral :)

    So, would it be Ba^(2-) ?? Sorry for asking so many questions. I just want to be sure.

    \[_{12}\text{Mg}^0 -2\times_0e^{-1} =~ _{12}\text{Mg}^{2+}\]
