| Herkunft des Namen: | |
| Beschreibung: | Soft, malleable, bright yellow metal. |
| Entdeckt von: | Schon in der Antike bekannt |
| Jahr: | -- |
| Ort: | Unbekannt |
| Quelle(n): | Found in veins in the crust, with cooper ore and native compounds. |
| Verwendung(en): | Very malleable. Used in electronics, jewelry and coins. It is a good reflector of infrared radiation, so a thin film of gold is applied to the glass of skyscrapers to reduce internal heating from sunlight. |
