I can't judge whether you are true :-)
I only can tell you that you are wrong.

So let's take NH4-: H has oxidation number +1 and the oxidation numbers have to sum up to the total charge of the ion, -1. That gives -3 for nitrogen. Same argument with C2O42-: Oxygen has oxidation number -2. Leaves me with +3 for carbon.

@DrDu - confusing typo in your post, it is NH4+ - unless it was premeditated :wink:
