Properties of Gold: Gold Element Facts As previously discussed, gold is a metal with great cultural and economic value. The high value of gold is due to its properties as a chemical element, which is determined by the composition of the gold atom. Composition of a Gold Atom From its entry...
Gold, a dense lustrous yellow precious metal and a chemical element of Group 11. Gold is attractive in color and brightness, durable to the point of virtual indestructibility, highly malleable, and usually found in nature in a comparatively pure form.
Gold is an unreactive metal and does not corrode easily. Items made from gold can survive for thousands of years and have even been found in good condition underwater. A metal’s resistance to corrosion is related to its position in the reactivity series. The more reactive a metal, the le...
