Metals such as_____are used for electroplating various objects such as bicycle parts and utensils.

Options

A. Copper
B. Uranium
C. Zinc .
D. Lithium

Answer

**Step-by-Step Text Solution:**

1. **Understanding Electroplating**: Electroplating is a process used to coat an object with a layer of metal. This is often done to enhance appearance, prevent corrosion, or improve wear resistance.

2. **Identifying Suitable Metals**: For electroplating, metals that are less reactive are preferred. This is because they can provide a protective layer without reacting with the environment.

3. **Analyzing the Options**: The given options for metals are:
- A) Copper
- B) Uranium
- C) Zinc
- D) Lithium

4. **Evaluating Each Metal**:
- **Copper**: It is a low-reactivity metal and is commonly used in electroplating due to its excellent conductivity and resistance to corrosion.
- **Uranium**: This is a highly reactive and radioactive metal, not suitable for electroplating.
- **Zinc**: While zinc is used in some electroplating processes, it is more reactive than copper.
- **Lithium**: This is also a highly reactive metal and is not used for electroplating.

5. **Conclusion**: Based on the reactivity series, copper is the most suitable metal for electroplating bicycle parts and utensils due to its low reactivity and corrosion resistance.

**Final Answer**: Metals such as **copper** are used for electroplating various objects such as bicycle parts and utensils.
