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.
