So, by the same logic, that means that all of our positively charged ions are, in fact, going to be smaller in terms of radius, compared to their neutral parents.

那么，按照相同的逻辑，我们所有的正离子，事实上，它们的半径都会缩小，与它们的中性母体相比。

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。
