    In the electrolytic series the metals are referred to as be more or
    less noble in regards to where they place in the series so therefore
    silver is more noble than iron iron is more noble than zinc etc. Both
    silver and copper are fairly high on the cathodic end of the series
    so they can be referred to as nobel metals.
