• So, the size still for an s orbital is larger than for a d orbital, but what we say is that an s electron can actually penetrate closer to the nucleus.

    轨道的尺寸比,p轨道还是要,但我们说的是s轨道可以,穿透到更接近原子核的地方。

  • I'm sure there's some upper limit as there are to most things, like if we think of wavelengths and different types of light, there is so large that you can get, but you would be approaching that level.

    我确信对于多数事物,都会有一个上限,就像我们考虑波长和不同的光时,那个太了,但是你可以接近那个量级。

  • You find that the graphs for the men and the women, the orange and the yellow lines look pretty much the same, so there don't appear to be any gender interactions until you get out here, and that's a pretty small segment of the population.

    图中黄色线代表男性,橙色线代表女性,两条线相当接近,除此之外,性别之间没有太差异,这部分人群总体并不多

  • There's some probability that it can get very, very close the nucleus, and that probability is actually substantial.

    有一定的概率,它能非常非常接近原子核,这个概率是相当的。

  • 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变的时候,从3s到3p到3d,我们可以发现只有s轨道,有很的概率,非常接近原子核。
