So, in order to fill our octet, what we do is put two on the nitrogen and two on the carbon.
因此,为了填满我们的“八隅体“,我们需要将两个放到氮上,将另外两个放到碳上。
To put it differently, in order to know what "Dogs" means, you never had to learn the word "Dogs."
换个说法,为了知道"狗狗们"的意思,你不需要去学"狗狗们"这个词
And this would sit on your belt. So it would sit like this and there would be batteries that you could either put in a fanny pack or there are all kinds of jackets you could wear in order to support the batteries,"

If, in fact, a gold nucleus was this size here, we would need to use another lecture hall in order to find a place to put this nucleus right here.
那么这个实验就太诡异了,所以我们决定,把距离压缩一下,我们要考虑到这一点。
Good programming style. All right? Things that we ought to do, as you put these pieces together in order to give you really good code.
优秀的编程风格,对不对?,为了得到真正优秀的代码,我们在把代码放到一起的时候。
Well, I just put them down in the order that came out of my head.
好的,我把它们,按照从我脑袋出来的顺序写下来的。
You've got to put some nice perfume onto it, in order for it to be useable, just as your soap would be pretty horrible without any perfume on it.
你要在其中加入好闻的香料,以便使用,就像肥皂,如果没有香味会很恐怖
If God gathers up all those small molecules, that had composed my body, reassembles them in the right order and put these calci molecules next to that hydrogen molecules, so forth and so on, reassembles them in a right way.
如果上帝重组了所有构成我肉体的,微粒分子,将它们以正确的次序重组,把大量的钙生分子和,氢分子放在一起,组合起来,将它们以对的次序重组。
How did we put our gene fragments into this plasmid DNA in order to make multiple copies of it, or to clone the gene?
如何把基因片段整合到质粒DNA上,来获得大量拷贝,或者说来克隆基因呢
So what that means is that's how much energy we would have to put into a hydrogen molecule in order to get it to split apart into its two atoms.
它的意义,就是我们需要向一个氢分子中注入这么大的能量,才能将它分解成两个独立的原子。
You got an extra hint here in terms of the order, so even if you had just forgotten what I said, sometimes it's not a terrible idea just to put it in the order it's written, that can give you a lot of clues as well.
其实大家还可以发现一个额外的提示,因此即使你忘了我刚才说的,有时候直接按照这个顺序,排列也不失为一个办法,这也可以给你很多提示。
This means in order to do that we actually have to put 7 kilojoules per mole of energy into the reaction to make it happen.
这意味为了完成上面的反应,我们不得不往里面注入,7,千焦每摩尔的能量。
The reason it's aluminum is because aluminum has a lower z effective, so it's not being pulled in as tightly by the nucleus, and if it's not being pulled in as tightly, you're going to have to put in less energy in order to ionize it, so that's why it's actually going to have the smaller ionization energy.
原因是,铝的有效核电量更少,所以没有被原子核束缚得更紧,而如果没有被束缚得更紧,你为了电离它所需要注入的能量也就更少,这就是,它的电离能会更低的原因。
If we have a higher z effective, it's pulled in tighter, we have to put in more energy in order to eject an electron, so it turns out that that's why case 2 is actually the lowest energy that we need to put in.
而如果有效核电量更高,原子核的束缚也就更紧,我们不得不输入更多的能量来打出一个电子,这就是第二种情况,所需要输入的,能量更少的原因。
putting all those things together, if you looked at this question again we'd get 100% on it, 0 9 that our only option here is 0. 9, and that it's not the negative, it's the positive version, because we're talking about how much energy we have to put into the system in order to eject an electron.
把这些放在一起,你们再看一下题目,大家100%都能选对,我们唯一的选择就是这个,它不是负数,它是正的,因为我们说的,是要,把电子激发出来,需要提供的能量。
I don't put them in any strategic order.
我并没有给他们安排了任何有策略性的顺序。
So, which has the smallest energy that you have to put in in order to eject this electron?
也就是,哪一项为了打出一个电子,所需要注入的能量最少?
So if we can figure out the binding energy, we can also figure out how much energy we have to put into our atom in order to a eject or ionize an electron.
所以如果我们可以计算出结合能,我们也可以计算出,我们需要注入多少能量到原子中,去逐出或电离一个电子。
I merge. And the merge is, put them in order.
合并的过程是将它们按顺序摆放。
Remember, because that 1 s orbital is all the way down in terms of if we're thinking about an energy diagram, we're all the way down here, so we have a huge amount of energy we have to put into the system in order to eject an electron.
还记得吧,因为1,s,轨道在能量示意图里,是在最底部的,我们要一直到最下面,所以我们要向这个系统注入非常大的能量,才能打出一个电子。
