So whether we finish it today, or more likely when we finish it up on Friday, once we get passed isoelectronic atoms, that's it, that's all you need to study for this first exam.

因此，我们也许今天讲完，或者更有可能周五讲完，无论如何，就到我们讲完等电子原子为止，这是你们第一次考试所需要准备的全部内容。

But we've been so completely socialized into thinking two things: one is that we need water with us all the time; and second we have to buy it.

但如今我们都对以下两个观念习以为常了,第一是我们每时每刻都需要水,第二是我们要花钱买水

That's great, but it's still not quite the picture we need, because actually, - all the electrons are not in equal orbitals -- one's in an s orbital, and 3 are in p.

这很好，但这还不是我们想要的图像，因为实际上，所有的电子不是在相同的轨道里的-,一个在s轨道里，3个在p轨道里。

It turns out we can express all these functions in terms of G, G we wouldn't need to choose G, but it's a very useful function to choose.

最终我们能把所有的这些函数,用自由焓G表示出来，我们没有必要选择，但是这个选择很有用。

So if, in fact, we want to describe a wave function, we know that we need to describe it in terms of all three quantum numbers, and also as a function of our three positional factors, which are r, the radius, phi plus the two angles, theta and phi.

实际上，我们想描述波函数，我们知道我们需要,用这三个量子数来描述它，同样，波函数还是,三个位置变量的函数，它们是r半径，还有两个角度theta和。
