It's thermal conductivity is second only to silver, because the single atom in it's outermost valence s orbital interacts readily to fill the shell with the relatively stable configuration of two electrons. Once we have the configuration for Cu, the ions are simple. What must happen to the calcium atom in order for this bond to form? 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. Therefore, the number of electrons in neutral atom of Copper is 29. Copper (Cu) has two valences Cu I (cuprous) has one valence electron and Cu II (cupric) has two valence electrons. Since ancient times, and possibly even before that, it has been extensively mined and used in a whole variety of capacities. The reason is obvious when we look at its atomic structure.
