热电子亲和力 thermoelectron affinity
负电子亲和势光电阴极 negative electron affinity photocathode
质子电子亲和力 proton affinity
但是,电子亲和能既可以是负的,也可以是正的。
Electron affinity, however, can be either negative or it can be positive.
这意味着氮的电子亲和能很低,它实际上并不愿意得到一个电子。
So this means nitrogen has low electron affinity, it doesn't actually want to gain an electron.
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 most of you recognize, if we switch back to the notes, that they do have a negative electron affinity.
Electron affinity is actually the ability of an atom, or we could also talk about an ion to gain electrons.
电子亲和能其实就是一个原子,或者我们也可以讨论离子获取电子的能力。
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 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?
