So do you think noble gases would have a high positive electron affinity, a low positive, or negative electron affinity?

那么，你认为稀有气体的电子亲和能,应该是一个高的正值，一个低的正值，还是一个负值？

- So most of you recognize, if we switch back to the notes, that they do have a negative electron affinity.

看来大部人都想到了，如果你翻翻讲义的话，它们的电子亲和能确实是负的。

So this is not going to be a favorable process, we're going to find that the electron affinity is actually a negative 7 kilojoules per mole for nitrogen.

因此这并不是一个容易发生的过程，我们会发现氮的电子亲和能,应该是负的，7，千焦每摩尔。

Electron affinity, however, can be either negative or it can be positive.

但是，电子亲和能既可以是负的,也可以是正的。

So, we were talking, however, about energy in terms of electron affinity, so we can actually relate electron affinity to any reaction by saying if we have this reaction written as here where we're gaining an electron, we say that electron affinity is just equal to the negative of that change in energy.

但是，我们现在讨论的能量,是电子亲和能，因，此我们可以将电子亲和能,与任何反应联系起来,只要我们将反应写成这种得到电子的形式，我们说电子亲和能就等于,反应前后能量变化的负值。
