| Legende |
| Herkunft des Namen: | Symbol aus dem Latein: cuprum (Insel Cypern berühmt wegen der Kupferminen) |
| Beschreibung: | Malleable, ductile, reddish-brown metal. |
| Entdeckt von: | Schon in der Antike bekannt |
| Jahr: | -- |
| Ort: | Unbekannt |
| Quelle(n): | Pure copper occurs rarely in nature. Usually found in sulfides as in chalcopyrite (CuFeS2), coveline (CuS), chalcosine (Cu2S) or oxides like cuprite (Cu2O). |
| Verwendung(en): | Most often used as an electrical conductor. Also used in the manufacture of water pipes. Its alloys are used in jewelry and for coins. |
