One of the main difference is is that when you're talking about multi-electron orbitals, they're actually smaller than the corresponding orbital for the hydrogen atom.

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。

OK. Binary search is perhaps the simplest of the divide and conquer algorithms, and what does that mean? It says, in order to solve a problem, cut it down to a smaller problem and try and solve that one.

好了，二分搜索也许是,最简单的分治算法，这意味着什么？,也就是说，为了解决一个问题,把它切割成小的问题,然后再来一个个解决。

The fact that the picture is a little prettier on the far right is testament to the fact that I'm sorting the left half, the left half, the left half, and that's why you get these little triangles, triangles, triangles, that then get merged together.

可以看到最右边的画面,变化很快,先对左半部分排序，然后再左半部分，这就是为什么会有这些小三角形，最后再将它们合并起来。

So let's do a quick clicker question, and you tell me how many valence electrons does fluorine have? Remember, valence electrons are different from core, they're only the outer-most electrons in the outer-most shell.

那么让我们来做一个小选择题，请大家来告诉我,氟有多少个价电子，要记得，价电子与芯电子不同，它们是在最外壳层的最靠外面的电子。

So again, what we see is the same pattern where the most probable radius, if we talk about it in terms of the d, that's going to be smaller then for the p, and the 3 p most probable radius is going to be closer to the nucleus than it is for the 3 s most probable radius that we're looking at.

同样的，我们可以看到相同的行为,ｄ轨道的，最可能半径，比ｐ轨道小，3p轨道的,最可能半径,比3s轨道离原子核更近。
