And let's say our second electron now is really far away, such that it's actually not going to shield any of the nuclear charge at all from that first electron.
距离原子核非常非常近,我们说第二个电子处于非常远的位置,这样它不会对第一个电子,感受到的来自原子核的电荷量有任何屏蔽作用,我们最后要说的是。
and holding the pen in the same hand in the close-up,
那么,在近距离拍摄的时候也应该是用右手拿笔,
They're not interacting at all so that's why the energy is the same as that for two individual atoms, that's what we're dealing with. As we get closer together, we start get lower and lower in energy.
它们之间没有任何相互作用,因此,体系的能量就等于两个分开的原子的能量,这就是我们要处理的,而随着我们的距离越来越近,我们的能量开始变得越来越低。
What does it mean to meet another person in such a close proximity?
跟一个人如此近距离的接触,是什么样的感觉?
So, your tongue is closer to your jaw than it is to your hip in the body; so too in both the motor cortex and the somatosensory cortex.
所以相对于屁股,你的下巴在身体上距离你的舌头更近,而在运动皮层与感觉皮层上的位置,也是这样对应着的
close to Copenhagen in Denmark and there, around there.
距离丹麦的哥本哈根比较近,在附近。
Well, you are quite close to Kensington High Street.
好的,现在你距离肯辛顿高街相当近。
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。
And that is not likely to be the case if it's the person who is nearby. Right?
这和我们说的,近距离产生爱情不是一回事儿?
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。
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。
