In this case, 6 valence electrons for each oxygen, so we have 18 total valence electrons.

So, in this case, we're just drawing the molecular orbital diagram for the valence electrons, so we have three for each.

For the carbon, we start with 4 valence electrons, we have 0 lone pair electrons minus 4, and we end up with a formal charge of 0.

OK PROFESSOR: Valence electrons. OK, sometimes you're going to be asked to draw a molecular orbital diagram where you're asked to include all electrons, and sometimes it will specifically say only include valence electrons.

教授：价电子，有时候你画一幅分子轨道图,有时候要求你画出所有的电子，有时候特别要求,只包括价电子。

So the 3 s 1, or any of the other electrons that are in the outer-most shell, those are what we call our valence electrons, and those are where all the excitement happens.

它们是经常发生激发情况的,那也是我们所看到，我们称之为价电子，它们是经常发生激发情况的。

And the idea is that when you do these Lewis dot structures, we're representing electrons with dots, which we'll see in a minute, and each dot is going to represent a valence electron.

而当你遇到这些路易斯点结构时，我们会将电子用点来表示，我们马上就会看到，每个点都代表了一个价电子。

So in terms of nitrogen that starts off with a valence number of 5, again we have 2 lone pair electrons in the nitrogen, and again, we have 6 electrons that are shared.

对于氮来说,我们应该从五个价电子开始，同样，氮也有两个孤对电子，共用电子的个数也一样，是六个。

So in oxygen again, this is just showing the valence electrons, so we end up having six valence electrons from each oxygen atom.

And to do this we're going to introduce valence bond theory, and the idea of hybridization of orbitals.

在这之前我们要引入价电子成键理论，和杂化轨道的概念。

In valence bond theory, the focus is on discussing the bonds, but it should look very familiar to you, because there's two types of bonds that we want to discuss here.

So, seven asks us if we have any valence electrons left, and how many valence electrons do we have left?

那么，第七步问我们是否还有价电子剩下，我们剩下了几个价电子？

So we have a total of 2, 4, 6, 8, 10 valence electrons, so I'll make sure I count to 10 as we fill up our molecular orbitals here.

我们一共有2，4，6，8，10个价电子，所以我一边填一边要确认,我数到10。

So in terms of remaining valence electrons we have 12, so we can finish off each of our Lewis structures, so that's our first structure there, and our second structure there.

那么关于剩下的价电子，我们有十二个，因此我们可以完成这两个路易斯结构了，那么这是我们的第一个结构，而那是我们的第二个结构。

And if we go on to step three where we figure out how many we would need for full octets, it's just going to be 2 times 8, so we have 16.

而如果我们继续到第三步,判断一下填满所有“八隅体“需要多少个价电子，结果应该就是二乘以八，也就是十六个。

So then in order to figure out the complete number of valence electrons in our molecule, we just add 5 plus 4 plus 1.

那么接下来为了得到,这个分子中价电子的总个数，我们只需要将五加上四，再加上一。

So we need to add those 2 valence electrons left as lone pair electrons in our structure.

因此我们需要将这两个剩下的价电子,作为孤对电子加到我们的结构中。

价电子的网络释义

价电子 价电子指原子核外电子中能与其他原子相互作用形成化学键的电子，为原子核外跟元素化合价有关的电子。过渡元素的价电子不仅是最外层电子，次外层电子及某些元素的倒数第三层电子也可成为价电子。价电子同时亦决定该元素的电导性能。一般来说，原子的价电子数愈少，活性就愈高。
