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。

Negative 1 plus 0 should add up to negative 1, if in fact, we're correct for the c n anion.

负一加上零应该等于负一，如果是这样，我们对于氰离子的结果就是正确的。

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, let's just figure this out for some of the examples we did, so for the cyanide anion.

那么，让我们来算一下已经,用过的一些例子的形式电荷，那么对于氰离子。

n And these are known as anions. It has the n, which might conjure up negative, or anion and minus both have five letters.

这些就是负离子，有，能让我们想起，负，这个字，或者负离子和负号都是5个字母。

It's possible to take the cation and anion and restore them to their neutral states.

我们可能得到阴阳离子,并把它们以电中性形式存在。

So, for example, just talking about hydrogen cyanide or the cyanide anion, these are both molecules which are used in organic synthesis, so particularly the cyanide anion and salts of the cyanide anion.

那么，比如，就拿氰化氢,或者氰离子来说，它们都是用于有机合成的分子，特别是氰离子和氰离子的盐。

Cation is plus one, anion is minus one.

阳离子带正电荷，阴离子带负电荷。

e The charge on the anion times minus e, so there is the minus e squared, 0R0 and divided by 4 pi epsilon zero r naught, because now I am evaluating this function at r naught, one minus one over n where n is the Born exponent.

阴离子的电荷乘以，因此会有-e的频繁，除以4πε,因为现在我用r圈评估这个函数，1-1/n，n是波恩指数。
