The World of Gold: From the Sky to the Earth
Gold, this precious and lustrous element, has had a significant impact on human history and its economy. Gold is defined as the chemical element Au, represented by the symbol Au in the periodic table, and it has an atomic number of 79. Despite its rarity and high cost, gold is found all over the world and has been used since ancient times in various industries and cultures.
Where Does Gold Come From?
Although gold may seem like a metal produced through complex manufacturing processes, it actually originates from outer space. Gold is naturally created during nuclear fusion processes inside stars. When a star advances in its life and enters its final stages, nuclear fusion processes occur under immense pressure and heat, leading to the formation of gold among the lower elements in the periodic table. When a star explodes in a process known as a supernova, gold and other heavy elements are released into space.
Extracting Gold from the Earth
After gold is formed in outer space, it can be collected by gravity and other natural forces and enter the Earth. Gold is found in underground rock formations and on its surface. Gold is extracted through complex mining operations, including rock blasting, crushing, and separating gold from impurities using chemical and physical techniques such as flotation and cyanide treatment.
Uses of Gold
Gold has multiple and diverse uses in today's world. Here are some common uses of gold:
- Jewelry: Gold is primarily used in the jewelry industry due to its luster and resistance to corrosion. Gold can be shaped into various forms to create rings, necklaces, bracelets, and other precious pieces.
- Electronics: Gold is used in the manufacturing of electronic devices because of its efficient electrical conductivity. Gold is used in computers, mobile phones, and sensors.
- Medicine: Gold is used in treating certain complex diseases such as rheumatoid arthritis through the injection of soluble gold into joints.
- Currency and Medals: Gold is used in coin minting and crafting luxury medals.
- Decorative Arts: Gold is used in paintings, decorative artworks, and sculptures.
The Gold Economy
Gold is considered one of the most important commodities in global markets. The price of gold is influenced by various factors, including supply and demand, economic and political fluctuations. Gold is also used as a store of value and a safe haven in challenging economic times.
Conclusion
Gold is not just a precious metal; it has a long and rich history in world cultures and economies. With its unique properties and versatile uses, it remains a shining element in our world today and will continue to do so in the future.
