Electrolytic reduction method is used fro the extraction of

Options

A. Highly electronegative elements
B. Transition metals
C. Highly electropositive elements
D. Metalloids

Answer

**Step-by-Step Solution:**

1. **Understanding Electrolytic Reduction**:
The electrolytic reduction method is a process used to extract metals from their ores. This method involves the use of electrical energy to reduce metal ions to their elemental form.

2. **Identifying the Type of Elements**:
The question asks which type of elements are extracted using this method. We need to consider the characteristics of the elements involved.

3. **Characteristics of Electropositive Elements**:
Electropositive elements are those that have a tendency to lose electrons and form positive ions. They are typically found on the left side of the periodic table and include metals like sodium, potassium, and aluminum.

4. **Application of Electrolytic Reduction**:
The electrolytic reduction method is particularly useful for extracting highly reactive metals, which are also highly electropositive. For example, aluminum is extracted using this method because it is very reactive and has a valency of +3.

5. **Conclusion**:
Based on the properties of the elements and the application of the electrolytic reduction method, we can conclude that this method is primarily used for the extraction of highly electropositive elements.

6. **Final Answer**:
The correct option is **option 3: highly electropositive elements**.
