    Specific charge = charge to mass ratio. The only charge of a nucleus is the protons, and the mass of the nucleus is the number of protons AND the number of neutrons (no need to even consider or acknowledge electrons as it's the specific charge of the nucleus).

    Subsequently, specific charge of the gold nucleus =
    proton number  \times charge of a proton / nucleon number (atomic mass)\times mass of a neutron or proton ( the same)
