Malleability is a measure of how easily a material can be hammered into thin sheets.Gold threads can even be used in embroidery.

The element symbol for gold-Au-comes from the old Latin name for gold, aurum, which means "shining dawn" or "glow of sunrise." The word gold comes from the Germanic languages, originating from the Proto-Germanic gulþ and Proto-Indo-European ghel, meaning "yellow/green." The pure element has been known since ancient times.Nearly all the gold on Earth came from meteorites that bombarded the planet over 200 million years after it formed.Gold is the only metal that is yellow or "golden." Other metals may develop a yellowish color, but only after they have oxidized or reacted with other chemicals.
