gold
nounA precious metal of a bright yellow color, and the most ductile and malleable of all the metals. It is the heaviest metal except platina; and being a very dense, fixed substance, and not liable to be injured by air, it is well fitted to be used as coin, or a representative of commodities in commerce. Its ductility and malleability render it the most suitable metal for gilding. It is often found native in solid masses, as in Hungary and Peru; though generally in combination with silver, copper or iron.
