We are expecting to see that it decreases because it's feeling a stronger pull, all the electrons are being pulled in closer to the nucleus, so that atomic size is going to get smaller.
我们将看到它是减小的,因为电子会感受到越来越强的吸引力，所有的电子将会被原子核拉得越来越近，所以原子半径将越来越小。

We all know that in a falling elevator, you definitely do not escape the pull of gravity.

You pull out your clicker, you do it, and then we'll get a nice little pie chart or a bar chart on the computer of your responses.
你们就拿出表决器,按一下,我们就能在电脑上得到一张饼状统计图,或者柱状统计图,代表你们的答案

We're working up farther and farther in these partials and we've got some of these notes right next to each other and they want to move to the stable notes so we're going to be hearing a lot of a note right above the tonic wanting to pull down to that tonic note.
我们进一步介绍了这些泛音,我们看到这些音符,彼此贴近,它们想要变成稳定的基音,所以,我们会听很多,高于基音的音符,想下行靠近这些基音

A kind of consequence of this is if we're thinking about a multi-electron atom, which we'll get to in a minute where electrons can shield each other from the pull of the nucleus, we're going to say that the electrons in the s orbitals are actually the least shielded.
这样的一个后果就是,如果我们考虑一个多电子原子，我们等会就会讨论到它,电子会互相,屏蔽原子核的吸引，我们说ｓ轨道电子,更不容易被屏蔽。
