    Hi,

    So I was reviewing how to do oxidation states and I read this...

    In the case of NO3-, three oxygen atoms add to -6. Nitrogen is therefore +5, because you need to have one negative charge left over.

    Why does there need to be one negative charge left over?

    Thanks in advance for any help.

    Awesome, thank you, is that just something you have to learn or is there a way to work out charges of compounds like this without using oxidation states?

    The overall charge of NO3 is -1 therefore N + 3O = -1.
