Electric charge and static electricity.

In this section we are dealing with two types of charges: protons and electrons. Protons are bound tightly in the center of an atom, but electrons can sometimes leave the ... harge, static discharge, and electroscope. A neutral object can become charged by gaining or losing electrons. If an object loses electrons, it is left with more protons than electrons. Static electri ... object. In static electricity, charges build up, but they do not flow. Friction is the transfer of electrons from one object to another by rubbing. Conduction is the transfer of electron from a charg ...
