Copper is a typical face-centered-cubic metal. In its pure state, it has extremely high electrical conductivity. Oxygen in copper causes a major reduction of conductivity. To investigate this issue further, I want to you to tell me whether oxygen atoms substitute for copper atoms, or if they enter interstitial sites.
