And, we're going to look at what happens as the chloride ion moves from infinity in towards the positive ion.

然后我们要看一下,当氯离子从无限远处逐渐靠近,这个正离子会发生什么。

If instead we had a positive ion, a cation, what we would have to do is subtract 1.

如果我们有一个带正电的离子，一个正离子，那我们就需要再减去一个。

So, basically any time we have a really high positive number of electron affinity, it means that that atom or ion really wants to gain another electron, and it will be very stable and happy if it does so.

因此，基本上无论什么时候,只要我们有一个很大的正的电子亲和能，这就意味着这个原子,或离子非常希望得到一个电子，如果它得到了，会变得更稳定更开心。
