And, of course, each of those electrons correspond to an electron coming out of a particular orbital.
当然，每个电子都对应着，它原来所在的一个特定轨道。
It makes sense that it's going to come out of the highest occupied atomic orbital, because that's going to be the lowest amount of energy that's required to actually eject an electron.
从最高占据轨道上，去掉一个电子是合理的，因为这样是发射一个电子，所损失的最低能量。
So in the case of 12 32, that is our highest kinetic energy, it's the smallest amount of energy it takes to pop an electron out of that orbital.
因此，1232是我们能够得到的,最高的动能，它是从这个轨道中,打出一个电子需要消耗的最低能量。

s -我们不用杂化它，它已经有而且仅有一个未配对电子在s轨道里。
And what I want to point out that we just figured out for molecular orbital theory, is that o 2 is a biradical, because remember, the definition of a radical is when we have an unpaired electron.
我要指出的是，我们刚利用分子轨道理论，指导了O2是二价自由基，因为记住，自由基的定义是，有个未配对的电子。
So we can think about what is our most loosely-bound electron, what's that highest energy orbital, and it's going to be the 2 p orbital, that's going to be what's highest in energy.
我们来想一想,它“束缚得最松“的电子是哪一个，能量最高的轨道是哪一个？,它就是，2，p，轨道，是能量最高的轨道。
And again, you'll notice that our energy is absolutely the same for an electron in that 2px and 2s orbital.
同样，你们会发现2px轨道的能量，和2s轨道是一样的。
So what that means is that we're limited in any atom to having two electrons per orbital, right, because for any orbital we can either have a spin up electron, a spin down electron, or both.
这意味着在一个原子内,每个轨道上可以有两个电子，对吧，因为对任何轨道,我们可以有自旋向上或者自选向下或者两者都有。
So, our first orbital that an electron 1 s must be coming from is the 1 s.
所以，我们的第一个肯定有电子，被打出的轨道是。
So for example, if you look at the 1 s orbital here, you can see that actually it is lower in the case of the multi-electron atom than it is for the hydrogen atom.
所以举例来说，如果你看到这里的1s轨道，你可以看到实际上，多电子原子情况的。
In both cases we're taking an electron out of the 2 s orbital.
在这两种情况下，我们都拿走了一个，2s，电子。
For example, for the 2 s, again what you see is that the multi-electron atom, its 2 s orbital is lower in energy than it is for the hydrogen.
举例来说对于2s轨道，在多电子原子，中可以看到，它的2s轨道的能量低于氢原子的。

铯133原子发射一个细的微波谱线当它的第55个电子从受激态轨道跳回基态时(跃迁)。
It is not result of spin pairing to form chemical bonds, Instead, transfer electron from the atomic orbital of taller energy to the moleen -lar orbital of lower energy.
在化学键形成时并不是电子配对的结果，而是电子从能量较高的原子轨道转移到能量较低的成键的分子轨道上使体系能量降低的结果。
So, which orbital would we take an electron out of if we were ionizing this atom here?
那么，如果我们要电离这个原子，应该拿走那个轨道上的电子？
Between electron density distribution of molecular frontier orbital energy and the substitute position, there were some dependencies.
发现前线轨道能量与分子的电子密度分布及取代位置均有一定依赖关系。
