Electron
Electrons take part in gravitational, electromagnetic and weak interactions. The electromagnetic force is strongest in common situations. Electrons repel (push apart) from each other because they have the same electric charge. Electrons are attracted to protons because they have opposite electric charge. An electron has an electric field, which describes these forces. The electricity that powers televisions, motors, mobile phones, basically everything (electric) is actually many electrons moving through wires or other conductors.
