The noble character of gold is a consequence of its low oxidation potential. The value of its electrochemical potential E o (reduction-oxidation or redox potential) is the lowest of any metal [].This means that gold in any cationic form, the common ionic state for a metallic element, will accept electrons from virtually any source (reducing agents) to form neutral gold …

Gold metal has a distinctive yellow color and is incredibly malleable and ductile. A single ounce of pure gold can be beaten out to a sheet that is about 300 feet square!! Pure gold is easily cut with a knife. Few elements react with gold under normal conditions and so most gold is recovered as small flakes of the pure element.
