So, in this case, we see that our formal charge is negative on the nitrogen, in this case it's negative on oxygen.

那么，在这种情况下，我们看到氮的形式电荷是负的，而在这种情况下，氧的是负的。

So for example, that might have a formal charge of negative 1, because to some extent it has gained that much electron density that it now has a formal charge that's negative.

比如，可能它的形式电荷为负一，因为在一定程度上它得到了这么多的共用电子密度，那么它现在就有了负的形式电荷。

You've got a positive charge here with a negative charge around it.

正电荷在这儿，负电荷在周围。

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。

And in this case, the tie-breaker goes to the molecule in which the negative charge is on the most electronegative atom.

而在这种情况下，我们需要进行“附加赛“,也就是看看分子中带有负的,形式电荷的原子是不是电负性最高的。

The center of excess negative charge on all of the dipoles is at the very center of the molecule.

多出来的键,的负电荷中心都集中在,分子的正中间。

The process took advantage of an electric charge differential existing between the polymer, which was positively charged, and the bacteria cells, which carried a net negative charge.

This, among other things, helps it to distinguish bacteria from human membranes, which have a less negative charge.

Both naturally carry a negative charge and repelled each other.
