• 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,我们看到的形式电荷是负的,而在这种情况下,氧的是负的。

  • So, if we talked about a nitrogen-nitrogen single versus double versus triple bond, the triple bond will be the shortest and it will be the strongest.

    因此,如果我们讨论的是之间的单键,双键与三键,那么三键应该是其中最短的一个,同时也是最强的一个。

  • 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.

    那么在我们的第一个结构中,我们发现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 that takes care of the hydrogen, what about between the carbon and the nitrogen?

    因此氢就被排除了,那么碳和呢?

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

    那么这里显示的是,我们能看出来是因为它有七个电子。

  • So, let's, for example, look at nitrogen. So n 2, we can do the chart here in green, so it's the green dotted line, and what we see is that we have now defined this energy as where the 2 nitrogen atoms are separated.

    那么,让我们举个例子,看一下那么氮分子,我们可以把它用绿色曲线画在这,这是绿色的虚线,可以看到,我们已经定义为零点能,当两个原子分离时。
