What is Gold?
Gold is a chemical element with the symbol Au (from the Latin aurum, meaning shining dawn) and atomic number 79. It is a highly sought-after precious metal which, for many centuries, has been used as money, a store of value and in jewelry. The metal occurs as nuggets or grains in rocks, underground “veins” and in alluvial deposits. It is one of the coinage metals. Gold is dense, soft, shiny and the most malleable and ductile of the known metals. Pure gold has a bright yellow color traditionally considered attractive. Gold forms the basis for a monetary standard used by the International Monetary Fund (IMF) and the Bank for International Settlements (BIS). The ISO currency code of gold bullion is XAU. Modern industrial uses include dentistry and electronics, where gold has traditionally found use because of its good resistance to oxidative corrosion. Chemically, gold is a trivalent and univalent transition metal. Gold does not react with most chemicals, but is attacked by chlorine, fluo
Gold is a metallic element with the atomic number 79 and the symbol Au. While the name gold comes from an Old English word meaning yellow, the symbol comes from the Latin aurum, which means “shining dawn.” On the periodic table of elements, gold is found in Group 11, along with silver, copper, and roentgenium, and in Period 6 between platinum and mercury. It is referred to as a “transition metal.” Gold is the most malleable, ductile metal. Described as yellow, gold is one of the so-called precious metals, along with gold and silver. Known from ancient times — along with mercury, sulfur, copper, silver, lead, and tin — gold was used as early as 6000 B.C. Early use included gold jewelry, for example bracelets and rings, as well as ornamentation. Its malleability means that its early use in any practical items was impossible, so its used was restricted to decoration. The civilizations that employed it included the Egyptians, the Greeks, the Mesopotamians, and the Romans. Gold is found in

With other numbers of metals or alloys such as copper or iron pyrite, copying gold color is easy. They will look just as the gold as the real 14k gold. So why pick 14k gold? The answer is easy. Gold does not change in color, rust or corrode or fade. Gold survives time. Also gold can be shaped to any size or shapes. However with gold’s flexibility has a drawback. Due to its flexible nature, gold’s strength in minerals or harness is near the bottom of the chart. Because of these weaknesses, gold is mixed with one or more additional metals to make it strong. We call this alloy; they are usually copper, silver, nickel. These alloys not only strengthen the gold, but determine the color of the gold. For example, yellow gold will contain copper, and white gold will have nickel, zinc and copper is mixed in. With these concepts, gold can come in many color such as pink gold or also know as rose gold, or purple gold etc.
