Electric Charge & Force Notes

On a small scale, objects are composed of atoms, which are composed of protons, neutrons, and electrons. Protons and neutrons are bound in the nucleus of an atom, while electrons are free to move about in an electron cloud that surrounds the nucleus. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge.
