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。

So, in this case, we see that our formal charge is negative on the nitrogen, in this case it's negative on oxygen.

那么这里显示的是氮，我们能看出来是因为它有七个电子。

So, nitrogen is shown here, we know that because it has 7 electrons.

那么在我们的第一个结构中，我们发现氮的形式电荷量是五减去四4,再减去二，因为我们开始有五个价电子，因此它的形式电荷量是负一。

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.

So, shared electrons are the ones that are shared between the carbon and the nitrogen, so we have 6 shared electrons, and we want to take 1/2 of that.

共用电子是那些在碳和氮之间,被它们共用的电子，那么我们有六个共用电子，然后我们要给它乘上二分之一。

We know that ionization energy is going to increase as we go across the periodic table, so that means carbon has a lower ionization energy than nitrogen which is right next to us.

我们知道电离能会随着周期表,向右而逐渐变大，因此碳的电离能比旁边的氮要低一些,那么就像我说的。

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。
