Gold (GOLD) is a single form of chemical element gold (chemical element symbol AU). It is a soft, golden, corrosive precious metal.
gold is one of the rare, most precious and most valued metals. Internationally, gold is generally based on ounces, and ancient China was used as a gold unit. It was a very important metal. It is not only a special currency for reserves and investment, but also an important material for the jewelry, electronics, modern communications, aerospace and air industry and other departments.
The chemical symbols of gold are AU, and the English code in finance is xauusd or GOLD. The name of the AU comes from a story of Aurora, a goddess of dawn in Roman mythology, means shining dawn.
black metal: has only three types: iron, manganese and chromium
non -ferrous metal: 1) Heavy metal: The general density is 4.5g /cm3 above, such as copper, lead, zinc, etc.; (2) Light metal: small density (0.53 ～ 4.5g/cm3), lively chemical properties, such as aluminum, magnesium, etc. (3) Precious metal: The content of the crust is small, the extraction difficulty, the price is high, the density is high, the chemical is stable in nature, such as gold, silver, platinum, etc. Such as tungsten, molybdenum, tadpoles, lithium, 镧, uranium, etc. I because rare metals are of great significance in modern industries
