So, when we get really close together, granted, there is a net positive negative charge with a Coulombic force of attraction.

当它们真正离得很近时，假设有一个带正负电的电荷,带有库仑引力。

So, if we think about the second case here where we have c n minus, now we're talking about a molecule with a net charge of negative 1.

那么，如果我们考虑的是第二个例子,也就是氰离子，那么现在我们讨论的是一个净电荷量为负一的分子。

So that means if we add up all of the formal charges within the molecule, what we would expect to see is that they sum up to give a net charge of negative 1.

那么这就意味着如果我们把这个分子中,所有的形式电荷加起来，我们应该会看到它们加起来,之后得到的净电荷量为负一。

And there is this separation which is a balance of attractive forces because the chloride is net negative and the sodium is net positive, but both of them, regardless of net charge, have electrons.

这里有一个平衡,引力的平衡,由于氯离子带有负的净电荷,钠离子带有正的净电荷，但是它们两个，没有考虑净电荷，电子。
