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 we can do this for any final charge we have, if we have a molecule that has a charge of plus 2, then all of the formal charges should add up to plus 2 and so on.

对于任意净电荷的情况,我们都可以这样做，比如假设我们有一个带两个正电荷的分子，那么所有的形式电荷加起来应该等于正二，等等。

So, an electron has a charge of negative e, we've written here and the nucleus has a charge of positive e.

我们写在这，原子核带正e的电荷,我们看到作用力。
