这里是我提到的，对于写电子构型，和以正确的顺序得到轨道能量。
These are all isoelectronic, they all have the same electron configuration. And we can also think about going back to atomic size for a second.
这些都是等电子的，它们都有相同的电子排布，而,我们还可以再回想一下原子尺寸的概念。

让我们来想一想，锂，钠，钾的电子排布，它们都只有一个价电子。
Then something that you probably have a lot of experience with is talking about electron configuration and writing out the electron configuration.
然后有一些事情是,你们可能有较多经验,那就是讨论电子构型以及,写出它们。
These are all isoelectronic, they all have the same electron configuration. And we can also think about going back to atomic size for a second.
这些都是等电子的，它们都有相同的电子排布，而，我们还可以再回想一下原子尺寸的概念。
So, for example, if we needed to figure out the electron configuration for titanium, 4s2 it would just be argon then 4 s 2, 3d2 and then we would fill in the 3 d 2.
所以举个例子,如果我们需要解出钛的电子构型，它会是Ar然后，然后我们填充。
So, that's actually the electron configuration we have when we're talking about copper and some other exceptions in the periodic table that you're going to be looking at.
因此，这才是铜原子真正的电子排布，而且我们在元素周期表中，会看到与铜原子类似的，其他例外的情况。
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, selenium 2 minus is what's going to be isoelectronic, because if you add two electrons to selenium, you'll get the same electron configuration that you have for krypton here.
负二价的硒离子将是等电子的，因为如果你给硒原子加上两个电子，你会得到,和氪原子相同的电子排布。
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。
So basically, at the time he was just going on size and then traits, but what we actually know today is that we can also order things in the periodic table by electron configuration.
基本上，在当时他只能通过大小,和特性来进行，但是现在我们已经知道了,我们还可以通过电子排布来对它们进行排序。
The answer to that is definitely no -- if they had the same electron configuration, they would, in fact be neon. But we can think about different ions that have this electron configuration.
答案是绝对没有-,如果它们具有相同的电子排布，那么它们，实际上,将都是氖，但是我们可以想一想,有没有其它离子具有这种电子排布呢？
