And I just want to point out here in terms of things that you're responsible for, you should know that the most probable radius for a 1 s hydrogen atom is equal a nought.

在这里,我想要指出的是，你们要知道氢原子１ｓ轨道,最可能距离等于ａ０

So what this means is that unlike s orbitals, they don't have the exact same shape at any radius from the nucleus.

这意味着和ｓ轨道不同，它们在离原子核不同距离处的形状不是完全一样的。

And so, therefore, all other things being equal, the first orbit should be at a smaller distance.

所以，如果别的条件都相同的情况下，第一轨道的距离会更小。

And what is discussed is that for a 1 s hydrogen atom, that falls at an a nought distance away from the nucleus.

我们讨论了对于氢原子１ｓ轨道，它的最可能半径在距离原子核ａ０处。

For example, when we're talking about radial probability distributions, the most probable radius is closer into the nucleus than it is for the s orbital.

举例来说当我们讨论径向概率分布时,距离原子核最可能的半径是，比s轨道半径,更近的可以离原子核有多近。

s And if we go ahead and superimpose the 3 s on top of the 3 p, you can see that the 3 s actually has some bit of probability density that gets even closer to the nucleus than the 3 p did.

如果我们继续将,重叠到3p上面，你们会看到3s事实上,有一点概率密度,距离原子核更近,比3p轨道。
