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？

youdao

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。

youdao

One major difference between electron affinity and ionization energy is that when we talked about ionization energy, remember ionization energy always has to be positive.

电子亲和能，与电离能之间最大的不同就在于，当我们提到电离能的时候，记得电离能总是正的。

So, for example, for the chlorine case, we would say that the electron affinity for chlorine is actually positive 349 kilojoules per mole.

比如，以氯为例，我们可以说氯的电子亲和能,应该等于正的，349，千焦每摩尔。

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。
