Planetary Bohr Model of Gold (Au)
Description
Soft, malleable, bright yellow metal.
Uses
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.
Sources
Found in veins in the crust, with cooper ore and native .
Pronounciation (English)
