Topic - Quick chemistry question

Kemics - on 26 Apr 2013
..I probably need to find a chemistry forum.


Ionic charge is represented Element(n)+/- e.g Mg2+

But if it's oxidation state, say Mg in MgO it becomes Mg+2 O-2

Basically. If it's a ionic charge, you put the numeric value followed by positive/negative? But if it's oxidation state you put +/- followed by value?

is this correct? Sounds stupid but it's the sort of stuff you lose marks for.
