It is a dense, soft, malleable, and ductile metal with an attractive, bright yellow color and luster that is maintained without tarnishing in air or water. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains in rocks, in veins and in alluvial deposits. Less commonly, it occurs in minerals as gold compounds, such as with tellurium as calaverite, sylvanite and krennerite. Gold resists attacks by individual acids, but it can be dissolved by aqua regia (nitro-hydrochloric acid), so named because it dissolves gold. Gold also dissolves in alkaline solutions of cyanide, which have been used in mining. It dissolves in mercury, forming amalgam alloys; is insoluble in nitric acid, which dissolves silver and base metals, a property that has long been used to confirm the presence of gold in items, giving rise to the term acid test. its widespread monetary and symbolic functions, gold has many practical uses in dentistry, electronics, and other fields. Its high malleability, ductility, resistance to corrosion and most other chemical reactions, and conductivity of electricity has led to many uses, including electric wiring, colored-glass production, and gold leafing. Applications: Monetary exchange, Investment, Jewelry, electrical contacts, Medicine, Electronics, Gold solder, electromagnetic radiation, Commercial chemistry, Gold alloys are used in restorative dentistry, especially in tooth restorations, such as crowns and permanent bridges

Applications:

Manganese has no satisfactory substitute in its major applications, which are related to metallurgical alloy 

use. In minor applications, (e.g., manganese phosphating), zinc and sometimes vanadium are viable 

substitutes.
