Gold is a metallic yellow noble metal with a melting point of 1064 degrees Celsius. Gold is extremely resistant to corrosion, and this is the reason you can find gold pure in nature. One of the only things that can dissolve it is aqua regia, a mixture of hydrochloric and nitric acid on a 3:1 ratio. It was discovered by ancient civilizations long ago.

Gold is most commonly used as an investment and in jewelry. Gold is also commonly used in the electronics industry. For example, your phone or computer has many parts in it made out of gold or a gold alloy.
