Understand that static charge is created by the transfer of charged particles between surfaces.
Recall that atoms consist of three main particles: protons (positively charged), neutrons (neutral), and electrons (negatively charged).
Recognize that protons and neutrons are located in the nucleus and are generally not free to move between surfaces.
Know that electrons are located in the outer regions of atoms and can be transferred from one surface to another.
Conclude that the movement of electrons from one surface to another is responsible for creating static charge.
