And the reason that we use it is that it is incredibly accurate, and allows us to very, very quickly predict and to predict accurately, in most cases, what the electron configuration of molecules are going to be.
我们用它是因为它极为精确，并且能让我们非常非常快地预测,而且是准确地预测，大多数情况下，分子应该具有的电子排布。

If a proton which has no mass can behave as a particle does it follow that an electron which has mass can behave as a wave?
如果一个没质量的光子能像粒子一样,具有质量的电子能否,表现得像波一样吗？
-
So they'd much rather just stay the way they are and not have another electron come on, and it turns out that halogens have the highest electron affinities.
所以它们更愿意保持在原来的状态,不愿意再增加一个电子,结果卤族元素具有最高的电子亲和能。
-
It means that we better get away from these deterministic models where we have a little electron here with its potential energy and its kinetic energy.
它的意思是我们最好远离,这些确定性模型,那里有一个小电子,它具有势能和动能。
-
- The answer to that is definitely no -- if they had the same electron configuration, they would, in fact be neon. But we can think about different ions that have this electron configuration.
答案是绝对没有-,如果它们具有相同的电子排布，那么它们，实际上,将都是氖，但是我们可以想一想,有没有其它离子具有这种电子排布呢？
-
So we can go ahead and think about, well, are there any other atoms that are going to have the same electron configuration?
那么我们可以开始想一想，好，有没有其它原子,具有相同的电子排布？
-
Place the non-bonding pairs on peripheral atoms first, which the higher average valence electron energy.
首先将孤对电子放在外围的原子，那儿具有较高的平均价电子能。
-
So, this is actually kind of neat to point out, because we all remember J.J. Thomson Thomson J J Thomson from our second lecture, and J.J. Thomson got a Nobel Prize in 1906 for showing that electrons exist in that they are particles.
所以，这个确实需要要指出，因为我们都记得第二堂课,讲到的,因为发现了电子具有粒子性,在1906年获得了诺贝尔奖。
-
All right, well, oxygen has the highest valence electron energy.
好吧，氧具有最高价电子平均能。
-
Cl We know that because the sulfur and the chlorine in the oxygen have different average valence electron energies, they'll have different electron affinities.
我们都知道因为S和,在氧气中,具有不同的平均价电子能，所以他们的电子亲和力也不同。
