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 then the potential energy, the energy is stored here due to the coulombic force of attraction between the electron and the nucleus.

然后说势能,位能其实就是,由电子和原子核之间的库仑引力而形成的能量。

The reason is because the predominant force at this point is going to be the attraction that's being felt between the nuclei and the electrons in each of the atoms.

这是因为这时候最主要的力,是吸引力，它来自于,其中一个原子的电子与另外一个原子的原子核之间。

The positive force of attraction of the electrons on the outside is greater and greater, and that pulls everything in.

所以对外层电子的吸引力,会越来越强，把电子们都向内吸引。

And we saw last day that we have a Coulombic force of attraction which you have seen before.

我们昨天学习到,我们有库仑引力,之前你们学过的。

So, if we think about the force that occurs between a positively and a negatively charged particle, what we have is essentially a Coulomb force, so we can describe this as a force of attraction.

一个带负电的粒子之间，的作用力,这本质上就是库伦力，我们可以把它，描述成一个引力。

If you look at the ground state in two different systems -If you look at the ground state which is n equals one, think about this, if I increase the proton charge, the Coulombic force of attraction is greater.

如果你观察两个不同系统的基态,当你观察n，等于1的基态时，试想一下，如果我增加质子电荷，相互吸引的库仑力就会更大。
