Understanding Noble Metals
Noble metals are a group of metals that are resistant to corrosion and oxidation in moist air. Let’s analyze the provided statements regarding noble metals.
Statement 1: Noble metals are found in pure form in nature.
- **True**: Noble metals, such as gold, silver, and platinum, can often be found in their native state (pure form) in nature. This characteristic distinguishes them from other metals, which generally exist as ores requiring extraction.
Statement 2: Uranium and lead are examples of noble metals.
- **False**: Uranium and lead are not classified as noble metals. Uranium is primarily known for its radioactive properties and is used in nuclear applications. Lead, while it has some resistance to corrosion, does not possess the qualities that define noble metals.
Conclusion
- Based on the analysis:
- Statement 1 is correct.
- Statement 2 is incorrect.
Thus, only Statement 1 is correct, making the answer option "D" (1 only) appropriate.
Key Takeaways
- **Noble metals**: Gold, Silver, Platinum (pure form in nature).
- **Non-noble metals**: Uranium and Lead do not qualify as noble metals.
- The correct answer is option **D** (1 only).

Noble metals
- These metals have high heat resistance, high corrosion resistance, high melting points, and unique catalytic properties.
- They are usually found in nature in their pure form. (Hence, Statement 1 is correct)
- Gold (Ag), Silver (Ag), Platinum (Pt) and Platinum metals are Noble metals. (Hence, statement 2 is incorrect)
- Here, Pt, osmium (Os), iridium (Ir), ruthenium (Ru), rhodium (Rh), and palladium (Pd), are collectively called platinum metals.
- Because they are so nonreactive, they don't corrode easily. This makes them ideal for jewelry and coins.
