Gold Gold is a chemical element with symbol Au (from Latin: aurum) and atomic number 79. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable and ductile metal.Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, and is solid under standard conditions.old's most stable isomer is 198m2 Au with a half-life of 2.27 days. Gold's least stable isomer is 177m2 Au with a half-life of only 7 ns. 184m1 Au has three decay paths: β + decay, isomeric transition, and alpha decay. No other isomer or isotope of gold has three decay paths.

Karated gold used in engagement rings can be from 100% gold to as low as 37% gold. Gold’s karat grade is used to express the proportion of gold in an alloy or the quality of a gold alloy.

- Caratage and Fineness: Understanding Gold Purity. Since pure gold is too soft to use for jewelry making, it is combined with other metals to make it stronger. Caratage and fineness both refers to the purity of gold in a gold alloy. Caratage signifies the number of karats in it, whereas fineness refers to parts per thousand of gold in an alloy.

How Gold Works Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals. A sample is then taken to a lab for tests, or assays, that measure the gold content. In most cases, the gold is 99.9 percent pure. Workers cast the gold produced during refining into bars. What happens next depends on how the gold will be used. Pure gold is generally too soft for most practical applications, so other metals are nearly always added to it.

- 6. Gold alloy – gold-colored mixture of gold, copper and other metals, and is used mainly for crowns, fixed bridges and some partial denture framework. 1  Advantages – good resistance to further decay if fits well; excellent durability-does not fracture under stress; does not corrode in the mouth.or more than 150 years, dental fillings known as amalgams have been widely used to treat tooth decay. Amalgam fillings are made of a mixture of metals. The ingredients include equal parts of elemental mercury (43 to 54 percent), and an alloy powder (46 to 57 percent) mainly composed of silver, tin, copper.
