And what you find is when you have a bonding orbital, the energy decreases compared to the atomic orbitals.

你们发现当你有个成键轨道的时候，相比原子轨道能量要降低。

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。

OK, what we'll see shortly is that this will allow us to see that for an isolated system the entropy never decreases.

好，我们过一会,会看到,这将导致孤立系统的熵,永远不会减小。

And note that as Z increases, as the proton number increases the radius decreases for a given n number.

并注意到当Z不断增加，对于一个给定的n，即当质子数增加的时候,半径的n值就减小了。

If there's a group, responsibility to help decreases and this is captured in different ways but the main idea is we all think someone else will help so we don't. There's a diffusion.

如果是一群人，帮助的责任就会分散变小,这体现在多个方面,但最主要的想法就是我们都认为别人会帮助,所以我们就不帮助了，责任被分散了。

It decreases. If you're still not completely up on the periodic trends, that is stuff that's going to be on the first exam, so make sure that you're able to do this without taking too much time to think about it.

它会降低，如果你还没有完全掌握周期性规律，而这是第一次考试要求的内容，因此请务必做到不用,想太久就能做到这点。

So if we're keeping n the same, we look and what we saw was that size actually decreases as we increase the value of l.

如果我们保持ｎ不变，我们看到随着ｌ值的,增大尺寸变小。

As we go down a column, what happens is that the ionization energy decreases.

当我们沿着列向下走的时候，会发现电离能是在降低的。
