Chemical Gold, AuGold is one of the most coveted and admired metals not only for its striking beauty, but for its unique physical and chemical properties. These properties make gold the metal of choice in various fields, including electrical, chemical, engineering, and medical industries.

Gold is a soft, pliant and dense metal, which is why it is a common material used to create jewellery pieces. Gold can resist corrosion and doesn’t easily rust. Jewellery pieces made of gold will not easily tarnish and would still remain beautiful over the years. Compared to other metals like copper, lead and silver, gold is more compact and is denser. It doesn’t react to other elements, making it an essential metal for jewellery. It is relatively softer than other metals and can be combined with other metals to create a harder and durable jewellery pieces. Gold is pliable so it can be easily moulded into any shape or design. It can be pelted to create intricate gold jewellery pieces.

In addition, it is also an excellent conductor of heat and electricity. It can be pelted into thin sheets and embedded into thin wires for electrical purposes. Because it can conduct both heat and electricity and can resist corrosion, it has also been used in the engineering and construction fields. Although it is quite an expensive metal, it has also been used in glass layers to protect cars and buildings from the sun’s thermal infrared radiations.

Moreover, since gold is non-toxic, small amounts of it can be used in food. In fact, European Union and United States have authorized use of gold labelled “food grade” or “additive E175” in food.

Gold has also many uses in the medical industry. Its chemical and physical properties make it a very valuable metal that medical experts use in a treatment called Chrysotherapy for rheumatoid arthritis patients. Because it is also believed to be rich in anti-aging properties, using of pure gold in skin treatments is becoming more and more popular today.

Normally, gold cannot be damaged by liquid solutions except for one – aqua regia, which contains hydrochloric acid and nitric acid. Other solutions like water or alkaline solvents won’t do the metal any harm.

The unique physical and chemical properties of gold make it a very valuable metal, which is one of the reasons millions of people use it as an investment.
