As she felt the doll with one hand I slowly formed the letters, d-o-l-l with my fingers in her other hand.

L Well, there is one L missing there.

可惜我的名字少了一个。

Yup, so one total node, 2 minus 1 is 1, and that means since l is equal to 1, we have one angular nodes, and that leaves us with how many radial nodes?

一个节点，２减去１等于１,因为ｌ等于１,我们有一个角向节点，那剩下径向节点有多少个呢？

Professor Irvine-Halliday used a one-watt bright white L.E.D.

And so, in this case, l could equal zero, 2 l could equal one or l could equal two.

所以这样的话，l可以等于，也可以等于1或。

So that's why we saw, for example, in the p orbitals we had one angular node in each p orbital, because l is equal to 1 there.

这就是为什么在ｐ轨道中,每个轨道节点数都是１,因为这里ｌ等于１．

So, it would be a good question to ask n why are we limited clearly there's this relationship between l and n, and we can't get any higher than n equals one.

那我们要问了,为什么我们被限制了，很明显，l和,有关系，为什么不能取到，n-1更大的值。

So when we talk about a wave function squared, n l m he wave function, any one that we specify between n, l and m, at any position that we specify based on r, theta, and phi.

一个波函数,的平方时，对特定,特定位置r，theta，phi波函数，取平方,如果我们取平方。

m And the third one is called m, l it's also m sub l.

And what you can see is that 0 for any n that has an l equals 0, you can see here how there's only one possibility for and orbital description, and that's why we don't need to include the m m when we're talking about and s orbital.

你们可以看到,对于任何n，如果l等于，你们从这里可以看到，只有，一种,可能的轨道描述，所以,当讨论s轨道的时候,不需要考虑。

By the way, l equals one would be the p-orbitals.

顺便说一下，l等于1时就到了p轨道的范围。

I think most and you are familiar with the Aufbau or the building up principle, you probably have seen it quite a bit in high school, and this is the idea that we're filling up our energy states, again, which depend on both n and l, one electron at a time starting with that lowest energy and then working our way up into higher and higher orbitals.

我认为你们大多数熟悉奥弗堡,或者构建原理，你们可能,在高中见过它，又一次,这是我们填充能级的观点，与n和l有关，一个电子每次从,最低的能级开始,然后以我们的方式上升到,更高更高的轨道。
