IDENTIFICATION

Gold is the most malleable of all metals; a single gram can be beaten into a sheet of 1 square meter, or an ounce into 300 square feet. Gold leaf can be beaten thin enough to become transparent. The transmitted light appears greenish blue, because gold strongly reflects yellow and red. Such semi-transparent sheets also strongly reflect infrared light, making them useful as infrared (radiant heat) shields in visors of heat-resistant suits, and in sun-visors for spacesuits. Gold is a good conductor of heat and electricity and reflects infrared radiation strongly.

ELEMENT BRIEF

Circa 9,000 BCE in the Middle East.

DISCOVERY

Anglo-Saxon 'gold' (origin of symbol Au is Latin 'aurum' meaning 'gold').
