2. Gold
Gold is a precious metal with the chemical symbol Au, derived from the Latin word aurum. It ranks third in electrical conductivity after silver and copper among all metals, as well as in heat conduction and light reflection. Gold is a resistant to oxidation, highly aesthetic metal with a bright yellow color.
Gold is favored in the jewelry industry due to its high durability, corrosion resistance, and ability to alloy with other metals to create various colors. However, due to its high cost and susceptibility to corrosion, it is not extensively used in the electrical industry. Instead, it is used as a store of value and in artistic creations.
In addition to its conductivity, gold possesses other special properties such as corrosion resistance, maintaining high stability, and resistance to inflammatory agents. These properties enable gold to be utilized in other fields such as electronics, medicine, and aviation. Gold is also a metal used to make prestigious awards like Olympic medals, Oscars, or Grammys.
