Why gold does not rust and always shines may be due to its special qualities. Even though it has been stored for a long time, gold can still shine and does not change color, unlike most other metals.
But what exactly makes gold so special and rust-free? Let's see the explanation below!
1. Gold is a Precious Metal
The main reason why gold does not rust is because gold is included in the type of precious metal . The precious metal itself is a metal that does not easily react to oxygen and water elements.
This special property of precious metals means that gold does not rust and will not change color over time.
2. Does not react with oxygen and water
Iron and metals in general react with oxygen and water, then form oxides that cause corrosion so that jewelry rusts.
However, gold has a more stable atomic structure, so it does not react with oxygen or water. This is one of the reasons why gold remains shiny and does not change color.
3. Has resistance to acids and bases
Metal or iron is very susceptible to corrosion when it comes into contact with acids and bases, because of its nature of reacting easily and being damaged quickly.
On the other hand, gold has better resistance to acids and bases, so it does not corrode easily.
4. Does not undergo oxidation
Another reason why gold doesn't rust is because it doesn't oxidize . Metals like copper will oxidize over time, causing them to darken to black.
On the other hand, gold is able to maintain its original color because of its nature which does not easily react with other elements in the air.
5. Does Not Absorb Moisture
Gold also does not rust because it does not absorb moisture. Unlike some types of metals that can absorb water or vapor in the air, gold remains stable and does not react with moisture.
This ability makes gold not easily corroded or discolored, so it remains shiny for a very long time.
Conclusion
From the various reasons above, gold is proven to be a special metal because it does not rust and remains shiny even though it has been stored or used for a long time.
Its nature as a noble metal, its resistance to oxidation, and its ability to resist reactions with oxygen, water, acids, bases, and moisture make it different from other metals that are prone to corrosion.
This is why gold is not only popular as jewelry, but also a top choice for long-term investment. With its timeless advantages, gold remains a symbol of luxury and durability.
