Noble metals are metals which have stable electronic configuration.They occur in free state and are non-reactable.

Noble Metals
Noble metals are a group of metals that exhibit high resistance to corrosion and oxidation in moist air. They are known for their exceptional luster and rarity, making them valuable for various applications. These metals are highly unreactive and do not easily tarnish, making them ideal for use in jewelry, electronics, and medical devices.

Characteristics of Noble Metals:
- High resistance to corrosion
- Excellent conductivity
- Low reactivity
- Good catalytic properties
- Lustrous appearance

Examples of Noble Metals:
1. Gold: Known for its beauty and malleability, gold is a highly sought-after metal used in jewelry, currency, and electronics.
2. Silver: Silver is valued for its conductivity and antibacterial properties, making it a popular choice for jewelry, silverware, and electrical contacts.
3. Platinum: Platinum is a dense, malleable metal with a high melting point, often used in catalytic converters, jewelry, and medical implants.
4. Palladium: Palladium is a rare metal with excellent catalytic properties, commonly used in catalytic converters, electronics, and jewelry.

Applications of Noble Metals:
- Jewelry making
- Electronics manufacturing
- Medical devices
- Catalytic converters
- Currency production
In conclusion, noble metals are a group of precious metals known for their resistance to corrosion, high value, and various applications in different industries. Their unique properties make them indispensable in modern society.
