其中最主要的区别之一，是当你讨论多电子轨道时，它们实际上，要比对应的氢原子轨道，要小一些。
youdao
7. 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。
youdao
8. 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。
youdao
9. 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。

10. S — we don't have to hybridize it, it already has only one unpaired electron in a 1 s orbital.
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。
youdao
11. 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.
12. 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.
13. 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。
youdao
14. 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.
15. 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。
youdao
16. 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。
youdao
17. 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。
youdao
18. 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。
youdao
19. This makes the system of orbitals unstable and an electron from an orbital further out rapidly fills the hole.
这使得轨道系统不稳定，外一层轨道的电子会迅速跃迁到内层空轨道上，填补空穴。
youdao
20. This paper analyzes shell electron pair repulsion theory , valence-bond theory and molecular orbital theory on molecular structure of noble gas compounds.
21. According to the classification of free radicals, the Character of the molecular orbital occupied by the unpaired electron was presented.
提出按未完成对电子占据的分子轨道特性对自由基系统进行分类。

22. Cesium-133 atoms emit a thin microwave spectral line when its 55th electron jumps back from an excited state orbital to its ground state (transition).
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)。
youdao
23. 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.
24. 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？
youdao
25. 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。
youdao
26. So here's the pneumonic I mentioned for writing the electron configuration and getting those orbital energies in the right order.
这里是我提到的，对于写电子构型，和以正确的顺序得到轨道能量。

用杂化轨道理论和分子轨道理论阐明了氮的氧化物成键类型，给出了分子空间构型及结构数据的解释。
youdao
28. So again, this is an anti-bonding orbital, and what you see is that there is now less electron density between the two nuclei than there was when you had non-bonding.
同样的，这是反键轨道，你们看到当你有反键轨道的时候，两个原子核中间的电子密度更小了。
