why is electricity able to pass through a penny, nickel, and a dime but can't pass through paper, foil, and plastic?

Assistance needed.

electricity is electrons. They can be conducted through metals, but not non-metals. Why? Because metals have atoms that allow electrons to be loosly attached and move, but kinds of atoms that don't allow this movement are without electron flow from atom to atom..they are non-conductors.
