One may need to watch it more than once to penetrate the different layers of the human condition.

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轨道还是要大，但我们说的是ｓ轨道可以,穿透到更接近原子核的地方。

So what is actually going to matter is how closely that electron can penetrate to the nucleus, and what I mean by penetrate to the nucleus is is there probability density a decent amount that's very close to the nucleus.

所以实际上有关系的是,电子可以穿越至原子核有多近,我所指的穿越至原子核是,这里有一定数量的概率密度,可以距离原子核非常近。

A small molecule gets produced by cells in one part of the body, circulates in the blood, estrogen enters cells, and sometimes that estrogen is able to penetrate deep within the cell, even into the nucleus.

Soon when we're talking about multi-electron atoms, and I just want to introduce it here, that it is sort of opposing ideas that even though the s is the biggest and it's most likely that the electron's going to be furthest away from the nucleus, that's also the orbital in which the electron can, in fact, penetrate closest.

当我们说多电子原子时，我这里要先介绍一下，这些概念有些相反,虽然ｓ轨道最大,所以电子最可能远离原子核，但它上面的最容易，穿透到离原子核最近。

And when we're talking about orbitals in the same state, what we find is that orbitals that have lower values of l can actually penetrate closer to the nucleus.

当我们谈论在相同态的轨道时,轨道事实上，我们发现的,是具有较低l值的,可以穿越到距离原子核更近的地方。
