    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:

    Thank you guys. I thought that carbon has a oxidation number of +4 in this compound.
    Thank you so much for help.
