It's somewhat different when we're talking about the p or the d orbitals, and we won't go into the equation there, but this will give you an idea of what we're really talking about with this radial probability distribution.

当我们讨论ｐ轨道或者,ｄ轨道的时候会有些不同，我们那时不会给出方程，但它会给你们一个,关于径向概率,分布的概念。

So, if I kind of circle where the probability gets somewhat substantial here, you can see we're much closer to the nucleus at the s orbital than we are for the p, then when we are for the d.

我把概率,很大的地方圈出来，你们可以看到在ｓ轨道上,比ｐ轨道更接近原子核，最远是ｄ轨道。

You'll have S block, P block, and D block elements.

有S区，P区和D区元素。

We did it for the s orbitals, we can also do it for the p, we can do it for the d.

我们对ｓ轨道这样做了，我们也可以对ｐ轨道这样做，对ｄ轨道这样做。

That's it. Again, these other p dxy dyz - or the d x y, d y z, those are going to be those more complicated linear combinations, you don't need to worry about them.

同样，这些p轨道,或者，它们是一些,很复杂的线性组合，你们，不用管它。

So, it's very easy to calculate, however, the number of radial nodes, and this works not just for s orbitals, but also for p orbitals, or d orbitals, or whatever kind of work of orbitals you want to discuss.

径向节点，的数量，这不仅对s轨道适用，对p轨道，d轨道，或者任何你们想讨论的轨道，都是适用的,它就等于。

But we haven't yet addressed why, for example, a 2 s orbital islower in energy than the 2 p orbital, or why, for example, a 3 s orbital is lower in energy than a 3 p, which in turn is lower than a 3 d orbital.

但是我们还没有强调为什么，举个例子一个2s轨道能量低于2p轨道,或者为什么，举例来说它依次低于3d轨道,屏蔽一个3s轨道的能量小于3p轨道。

So if we compare l increasing here, so a 3 s to a 3 p to a 3 d, what we find is that it's only in the s orbital that we have a significant probability of actually getting very close to the nucleus.

我们比较当ｌ变大的时候，从３ｓ到３ｐ到３ｄ,我们可以发现只有ｓ轨道,有很大的概率,非常接近原子核。

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。
