而q1等于钠离子所带电荷量。

And, q1 is equal to the charge on sodium.

记住，e代表元电荷，而非电子所带电荷。

Remember, e represents the elementary charge, not the charge on the electron.

它们质量极小，不带电荷，可以穿透几乎任何物体而不留痕迹。

They have a minuscule mass, no electric charge, and pass through almost any material as though it was not there.

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。
