What is Metallic Gold?
Metallic gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the most valuable and sought-after elements in the periodic table. It is a soft, dense, yellow metal with a high luster and a melting point of 1064 degrees Celsius, which makes it easy to shape, mold, and cast. Gold is known for its ductility, conductivity, and resistance to corrosion, making it ideal for various applications, including jewelry, coins, electronics, and medicine. Currently, most of the world’s gold supply comes from mining or recycling.
The History of Metallic Gold:
The history of metallic gold is as fascinating as it is ancient. The earliest records of gold use date back to 2600 BCE in Egypt, where the pharaohs believed that gold was the flesh of the gods and buried their dead with vast amounts of it.
