So, if you can flip your lecture notes over and just write on the blank space, we're going to cover electronegativity first here, and specifically, you can go back and fill this in to your lecture 9 notes, if you want to stay organized, but I just suggest just writing it on lecture 10 notes now and going back.
因此,请大家把讲义翻到背面,就在空白处做一下笔记,我们要先讲一讲电负性,特别提醒一下,大家可以,回到第九课的讲义并把这些记在那里,如果你想保持条理性的话,但是我建议大家先写在第十课的讲义上,回去再记到第九课的讲义上。
that they might, you know, flip out about on another day.
可能在其他时候他们会为之抓狂的事情。
This completely could change if you were to flip from one to the other conformation which can happen in chemical reactions.
在化学反应中,它们的形状,可以从一种折叠成另外一种。
If you flip the Periodic Table over you will have the ionization energy of sodium, first ionization energy, 5eV and it is about 5 eV which, when you convert, 496kJ/mol is a whopping 496 kilojoules per mole.
如果浏览周期表,你可以得到钠的离子化能,第一电离能,大约,当你转换的时候,是巨大的。
We'll assume that if there's a tie that we flip a fair coin or a Supreme Court judge, whatever you want to take, whichever.
我们将假设如果有人票数一致,我们就掷硬币或由最高法院裁决,不论你们想用那种方法
You all flip it.
你们都把硬币抛起来。
All right. If you flip to the second side of your handout, you'll see that I have a piece of code there, that does this-- let me, ah, I didn't want to do that, let me back up slightly- this is the algorithm called search.
你可以看到实现这个功能的代码,让我,额,我不想这么做,让我们回来一点,这就是命名为search的算法-,我们来看看这个算法吧。
Unless you take the things that you don't like about this world and you flip them upside down and you can start that today.
除非你把在这世上讨厌的事物,翻转过来,你们可以从今天开始。
Once you've got that, you can do minus 7 times a vector Just take the vector, multiply it by Pi and flip it over.
明白这点之后,你就可以计算-7乘以矢量,只需用 π 去乘以那个矢量,然后将其方向调转
And that way you can flip around in it a lot easier."
这样翻起来就容易多了“
So if you flip the info page over on the back here, what you'll see is the periodic table, this is the same one that I've handed out in the last two lectures - the periodic table without any electron configurations.
将这张纸翻过来,你可以看到一个元素周期表,这与我们前两次课发过的,是一样的,-没有任何电子排布的周期表。
So that's just a little bit of a check for yourself, and it should make sense because what you're doing is you're calculating the difference between energy levels, so you just need to flip around which you put first to end up with a positive number here, and that's a little bit of a check that you can do what yourself.
所以你们总要确保括号,离得这项是正的,这是你们自己,可以做的检查,这事很有道理的,因为你们做的是计算能量差,所以你需要调整顺序来保证一个正数,这是你们自己可以做的检查。
The best study to show this is a quiz show study, which is you take two people and you flip a coin.
这个理论的最佳研究就是一个问答节目研究,找来两个人,抛硬币。
