conductor of electricity. If the electrons in an atom can’t be moved from their orbits at all‚ the material is an insulator. If at least some of the electrons can be moved‚ the material is a resistor. Two of the best-known conductors of electricity are silver and copper. The atomic structures of the silver and copper atom are compared in Figure 6. Note that both atoms have only one electron in the outermost orbit. This makes silver and copper excellent conductors of electricity. Silver is
