First we can do that by knowing the electron configuration, we can write it out just by going up the table here, up the energy levels.

首先我们知道了电子构型，我们可以从，能量最低处开始填。

So we can write out what the electron configuration is here, and I think that I have already written that out for you in your notes.

我们可以在这里写出电子构型，我觉得我已经在你们,讲义上写出来了。

And we can also write this in an even simpler form, which is what's called electron configuration, and this is just a shorthand notation for these electron wave functions.

而且我们也可以将它，写为一个更简单的形式，它叫做电子构型,这个仅仅是这些电子波函数的。

So if we think about what we would do to actually write out this configuration, we just write the energy levels that we see here or the orbital approximations.

如果我们考虑我们所做的去,实际写出电子构型，我们只是写出我们看到的能级,或者是轨道近似就可以了。

So let's do this considering, for example, what it would look like if we were to write out the electron configuration for oxygen where z is going to be equal to 8.

我们来做这个考虑，举例来说,如果我们写出,有效电荷量为8的氧的电子构型。

So, if we want to think about what the first ionization energy is of boron, what you want to do is write out the electron configuration, because then you can think about where it is that the electron's coming out of.

如果我们要考虑,硼的第一电离能，你首先要做的是写出它的电子排布，因为在这之后,你才能知道拿走的是哪里的电子。

The first thing we need to do is write the electron configuration for the atom itself, and then we need to take an electron away.

首先我们要做的是,写出原子的电子排布，然后，我们再拿走一个电子。

So here we're talking about v plus 1, so if we were to write it just for the neutral electron itself, we would find that the electron configuration is argon, that's the filled shell in front of it.

这里我们要分析的是正一价的钒离子，因此，我们先写出中性原子的电子排布，可以发现，其原子实是氩原子的电子排布，这些壳层已经被占满了。

They're very deep and held very tightly to the nucleus, so we can often lump them together and instead of writing them all out separately, 3s1 we can just write the equivalent noble gas that has that configuration.

它们非常深,被原子核吸得很紧，所以我们通常可以把它们混在一起,而不是把它们写开，我们可以写出氖然后3s1所以,或者任何的一个。

So, no matter whether or not you write out the full form here, or the noble gas configuration where you write ne first or whatever the 3s1 corresponding noble gas is to the core electrons, we always write out the valence electrons here.

所以无论你是否,写出了完整形式，或者对应于价电子的惰性气体,再一次,我们可以写Ne然后，我们总是可以在这里写出价电子。

So if we write the electron configuration you see that this is the electron configuration here, 1s22s22p 1 s 2, 2 s 2, 2 p 6, 3s1 and now we're going into that third shell 3 s 1.

现在我们来到第三层,你们会看到3s1价电子之间的区别，电子构型是，现在我们来到第三层。
