text: This model may account for: Conductivity: Since the electrons are free, if electrons from an outside source were pushed into a metal wire at one end (Figure \(\PageIndex{2}\)), the electrons would move through the wire and come out at the other end at the same rate (conductivity is the movement of charge).
text: The electrons then move through the wire back to the positive pole (shown in copper) of the battery, and re-circulate.
