So, in this case, we see that our formal charge is negative on the nitrogen, in this case it's negative on oxygen.
那么，在这种情况下，我们看到氮的形式电荷是负的，而在这种情况下，氧的是负的。
2
So what we see is that the formal charge on the nitrogen is 0.
因此我们看到氮的形式电荷是零。
3
So in our first structure, we would find for the nitrogen we have a formal charge 5 minus 4 minus 2, because we're starting with 5 valence electrons, so that is a formal charge of minus 1.
