The Electric Force. See all that stuff around you? Everything.It's all made of just three things: protons, electrons, and neutrons. That's kind of wild when you think about it.

This force will act on any charged particle in the electric field around the generator. Image caption, A Van de Graaff generator removes electrons to produce a positive charge.

Electric forces underlie all of chemistry. Ultimately, it is the rearrangement of charges and their associated electric fields that governs chemical reactivity.

The electron attempts to pull away, but an electric force forms between the two to prevent the separation — like a dog pulling on a leash. This electric field is tugging in both directions, or ...
