Gold
Gold is dense, soft, shiny and the most malleable and ductile pure metal known. Pure gold has a bright yellow color and luster traditionally considered attractive, which it maintains without rusting in air or water.
It occurs as nuggets or grains in rocks, in veins and in alluvial deposits. A good thermal and electrical conductor, gold is generally alloyed to increase its strength. It is used as an international monetary standard, in jewellery, for decoration, sculpture and as a plated coating on a wide variety of electrical and mechanical components.
