This cation is attracting the chloride next to it and it is repelling the sodium as the next nearest neighbor.
这一阳离子被邻近的氯离子所吸引,并排斥钠离子,因为这是其最邻近的离子。
-
We've seen so far that we can have a neutral plus neutral sodium plus chlorine goes to cation plus anion.
到目前为止,我们得到了一个不带电的加一个不带电的,即钠加上氯，得到阳离子加阴离子。
-
If instead we had a positive ion, a cation, what we would have to do is subtract 1.
如果我们有一个带正电的离子，一个正离子，那我们就需要再减去一个。
-
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。

Now what I am going to do, this is off of just that one central cation.
接下来，这只是对一个中心阳离子的推导。
