First, real gold is not afraid of fire: the stability and fire resistance of gold.
Since ancient times, gold has stood out among many metals with its stable properties, and its most remarkable feature is fire resistance. In the traditional saying that "real gold is not afraid of fire", people have realized that gold is not easy to be oxidized at high temperature. This is because the gold atoms in metal crystals are arranged very closely, which makes it difficult for the outside electrons to be oxidized.
Even at high temperature, gold atoms can maintain their stable electronic structure and are not easy to react with other substances. This stability enables gold to keep its original state under various environmental conditions without corrosion or discoloration.
Second, real gold is not afraid of fire: the chemical stability of gold
The chemical stability of gold is one of its unique physical and chemical properties. Compared with other metals, gold is not easy to react with substances such as oxygen, acid and alkali. Even in high temperature or corrosive environment, gold can maintain its chemical stability and is not easy to be oxidized or corroded. This chemical stability makes gold widely used in jewelry, electronics, aviation and other fields.
Third, real gold is not afraid of fire: the preciousness and value of gold.
Gold has become one of the most precious metals in human history because of its rare and stable characteristics. Because of its unique physical and chemical properties, gold has important value in human society. It is not only a raw material for jewelry and electronic products, but also an important asset for reserve currency and investment. Because of its preciousness and value, people often regard gold as a symbol of wealth and social status.
