Copper - Wikipedia

Copper, silver, and gold are in group 11 of the periodic table; these three metals have one s-orbital electron on top of a filled d-electron shell and are characterized by high ductility, and electrical and thermal conductivity.The filled d-shells in these elements contribute little to interatomic interactions, which are dominated by the s-electrons through metallic bonds.
