It is 1.7475. Conclusion: if I start to react sodium with chlorine, the result is a crystal, a three-dimensional array.
这是1。7475，结论就是：,如果我使钠和氯反应，结果将会是一个晶体，一个三维排列。
-
It deconvolves that reaction of sodium plus chlorine into elementary steps that are related to electron transfer and acquisition.
它将钠和氯的反应,分解成基本的步骤,这些步骤是直接与电子的转移和获得有关的。
-
The ones that are most important in physiology are ones that only allow ions to go through: sodium, potassium, chloride, calcium, bicarbonate.
在生理学上这种,只能允许某种离子通过的通道十分重要,这些离子包括钠离子,钾离子,氯离子,钙离子和碳酸氢根离子
-
So now, let's get a sodium here, and the chloride ion next to it to the point where they are touching.
所以，我们要有一个钠离子，和氯离子放在,相互接触的一个点上。
-
And so what you're going to end up with is, well, let's go over that. Here is sodium and chloride.
你将以之结尾，好吧，我们跳过那个，这是钠和氯。
-
I think I had managed to get to this point here where I show what happens when the cation, here sodium, is in contact with the anion here, chlorine.
我想我能回到这儿,当阳离子，在这里是钠，和阴离子，氯离子接触会发生什么。
-
So, the sodium over here and the chlorine over here, they will be attracted to one another.
当钠离子和氯离子在一块时，它们会相互吸引。
-
And so you can imagine that if you mix these, if you take sodium and you mix it with chlorine you get sodium chloride.
如果将它们混合，以钠和氯反应为例,就会反应得到氯化钠。
-
So, what if we were to put the two of these in the same room?
所以如果我们,把钠和氯放一块会发生什么呢？
-
We see that we get a negative energy by attaching the chloride to the sodium.
我们得到了负能量,通过将氯和钠结合在一起。
-
I want to get to there starting from real sodium and real chlorine.
我们要实现这一步,从实际的钠和实际的氯开始。
-
Well, I show you one sodium and one chloride.
我给你看一个钠，和一个氯。
-
We get another chloride and another sodium sticking to the chloride.
我们得到另外一个氯和另外一个钠,固定在氯上面。
-
Sodium solid plus chlorine gas.
固态钠和气态氯。
-
So, sodium, chlorine attaches.
把钠和氯放一起。
-
So, for example, if I have a sodium ion over here, and I have a chloride ion over here, where the distance from center to center r I'm denoting as r, this is nucleus to nucleus separation.
所以，比如这有一个钠离子，和一个氯离子，它们中心与中心间的距离,我把它设为，这是原子核和原子和的间距。
