And when we do that we can see this curve, this probability curve, where we have a maximum probability of finding the electron this far away from the nucleus.

当我们这样做时，我们可以看到这个曲线，这个概率分布曲线，这里有发现,电子的最大概率。

So we can do this for any final charge we have, if we have a molecule that has a charge of plus 2, then all of the formal charges should add up to plus 2 and so on.

对于任意净电荷的情况,我们都可以这样做，比如假设我们有一个带两个正电荷的分子，那么所有的形式电荷加起来应该等于正二，等等。

We make inferences to the existence of things we can't see, when doing that helps us to explain something we can't otherwise explain.

我们推断一些看不到的事物的存在,因为这样做可以便于我们,解释某些我们不相信就无法解释的事情

So now in this problem, we can do something slightly different, and let's use this expression here,and I will do that, then I'll stop for today.

对于这个问题,我们可以稍微做点变化,让我们用这个式子,就是这样,今天就讲到到这里

But you could. So we were with races monkeys for 2 reasons.

但是你们可以这样做，我们之所以用猴子来做试验有两个原因。

We can keep doing this again and again.

我们可以一直这样做下去。

We did it for the s orbitals, we can also do it for the p, we can do it for the d.

我们对ｓ轨道这样做了，我们也可以对ｐ轨道这样做，对ｄ轨道这样做。

So it does that for us so that you can get away with just knowing the address of the first byte and it will make sure that you know when to stop by including the special value so, in fact, get the string if you type in a three-letter word, we allocate four bytes no matter what because we need an additional byte 0 for this special sentinel value back slash zero at the very end.

它为我们做了这些事情，这样我们就可以,通过第一个字节的地址,它还可以通过包含一个特殊的值,来保证在哪里停止，如果你输入了一个三个字母的单词,就可以获得那个字符串，不管怎样，我们分配四个字节,因为我们在末端需要一个额外的字节,来保存这个特殊的标志值--反斜杠。

So now we're putting 2 electrons into the same p orbital, that's not a problem, we can do it, it's not a huge energy cost to do that.

现在我们在同一个，p，轨道上放了两个电子，这没问题，我们可以这样做，这样不会亏损太多能量。

You're not going to start for the rest of your life if you ever need to solve a problem with a computer from scratch, odds are you're going to reach for some off the shelf packages or libraries or tools that other people wrote so that people like us don't have to reinvent the wheel again and again.

如果你想用Scratch来解决问题,却使用其他人写的程序,或者利用现成的资料或工具,这样以来,我们的确可以避免做重复性的工作,但却永远学不会编程。

As long as we understand that, we can do this cancellation and this says on the left-hand side the change in the quantity v square over 2 is a times the change in the quantity x.

只要我们明白这一点,我们就可以这样做简化,在等号左边,v^/2的变化量,为a乘以x的变化量

So let's do a sample calculation now using this Rydberg formula, and we'll switch back to emission, and the reason that we'll do that is because it would be nice to actually approve what we just saw here and calculate the frequency of one of our lines in the wavelength of one of the lines we saw.

让我们用Rydberg公式,做一个例题，我们回到发射上,这么做是因为这样,可以用我们看到的波长,来验证我们计算的频率。

So if we do this and we form the molecule ammonia, let's switch to a clicker question, and have you tell me what the bond angle - is going to be in ammonia -- HNH Actually, let me draw it on the board as you look -- actually, can you put the class notes on, since you don't actually have your notes to refer to.

如果这样做的话，我们就可以形成氨分子，让我们来做一个课堂练习,你们告诉我氨分子中的键角是多少-,键角，the，h，n，h，bond，angle。,实际上让我在黑板上画出它来，这样你们可以看到实际上-,你能把课堂讲义放出来吗，因为你们没有讲义可以参考。
