It’s just that the total area of sites with positive and negative charges are roughly equal (the two are typically within a fraction of a percent of each other).
只是带正负电的区域总面积是大致相当的（差别不超过千百分之一）。
Between these two tiny particles, the proton and the electron, there is a powerful attraction that is always present between negative and positive electric charges.
在质子和电子这两个微粒之间有一个很大的吸引力，而这个吸引力总是存在于正、负电荷之间。
