Problem
The screened-Coulomb golden-rule calculation for a charged solute in copper gives a residual resistivity per atomic per cent that scales as (ΔZ)2, where ΔZ is the difference in valence between the solute ion and the host copper ion, because the scattering matrix element is proportional to the solute's excess charge. For a solute with ΔZ=1 this calculation gives ρ0=1.8μΩcm per atomic per cent. Using this scaling, estimate the residual resistivity per atomic per cent contributed by a solute with ΔZ=3 dissolved in copper.
