The number of electrons on the surface of an object can make it have a negative charge or a positive charge. If the surface has more electrons, the object is negatively charged (-). If the surface has fewer electrons, it has a positive charge (+). A negative charge can build up on an object when electrons move to it from another object. This build up of electric charge on an object is called ________________ ___________________ .
