So, it turns out that in this case, 2 p and any time that we see we're going from a 2 s to 2 p, filling in of electrons, we actually see that little bit of glitch in ionization energy.

在这种情形下的结果就是，任何时候我们从，2，s，到，填充进电子，我们都会看到电离能会稍稍偏离我们的规律。

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。
