一提到这点你就应该立刻想到，我们并没有一个真正的原子半径，可以讨论，对吗？
So, keep that in mind when we're talking about atomic radius, I'm not suddenly changing my story and saying, yes, we do have a distinct radius.

We talked about ionization energy, electron affinity, we talked about electronegativity, which is just kind of a combination of the first two, and then ended with atomic radius here.
我们讲了电离能的，电子亲和能的，还讲了电负性的，也就是前两个的组合，最后讲了原子半径的。
We'll then take a turn to talking about the periodic table, we'll look at a bunch of periodic trends, including ionization energy, electron affinity, electronegativity and atomic radius.
然后我们再开始讲元素周期表，我们会看到很多周期性规律，比如电离能，电子亲和能，电负性以及原子半径。
So we haven't gotten to molecules yet, we're just talking about single atoms or single ions, but what's nice is just talking about this very straightforward principle of atomic radius.
我们还没有开始讲分子，我们仍然只是在讨论单个原子或离子，但它的好处在于可以讨论，这个关于原子半径的非常简单直接的原理。
And all ion channels are selective for a single type of ion, and we can think about how that selectivity takes place, and that's where this idea of atomic radius is going to become very important.
所有的离子通道都是仅对某一种离子具有选择性的，而我们可以来想一想这种选择性是如何发生的，这也就是原子半径这个概念将会变得，非常重要的地方。
So as we go down we're now adding electrons to further and further away shells, so what we're going to see is that the atomic radius is going to increase as we're going down the periodic table.
当我们向下走时，我们会将电子加在越来越远的壳层上，因此我们将看到原子半径，将随我们沿周期表向下走而增大。
In other words, just want to know where the electron is somewhere within the shell radius of the ground state of atomic hydrogen anywhere.
