However, it was difficult to determinate electron affinity by experimental methods.
从电子亲合势的研究发展历史看来,用实验方法测定电子亲合势是比较困难的,而且有些分子的电子亲合势用实验的方法不能精确测得,或者由于分子的不稳定性根本无法观测。

N a measure of the ability of an atom or molecule to form a negative ion, expressed as the energy released when an electron is attached 电子亲和势 ( symbol: )
Number four, electron affinity.
数字4,电子亲和力。
So this reaction is called electron affinity.
整个这个反应称为电子亲合。
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。
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?
