All objects are made up of atoms, and all atoms contain positive particles (protons) and negative particles (electrons). And yet atoms don't have an overall charge. They are neutral. That's because atoms contain the same number of protons and electrons. So the positive and negative charges are cancelled out. - - - - - - -

Static electricity is caused by a material having too many or too few electrons. When insulating materials (poor conductors of electricity heat) are rubbed together, outer electrons are knocked off one of them and onto the other. - - - - - - - - - - Rub Rub! The insulators become electrically charged. One positively charged due to a lack of electrons and one negatively charged due to excess electrons. Note: electrons are on the outside surface for insulators with everywhere for conductors

If the negatively charged insulator comes into contact with a conductor (good conductors of electricity heat), then the electrons move towards the conductor! Note: electrons are on the outside surface for insulators with everywhere for conductors - - - - -
