Options

A. Normal metals
B. Transition metals
C. Active metals
D. Highly electropositive

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Coinage Metals":**
- Coinage metals refer to specific metals that are traditionally used to make coins. They are known for their resistance to corrosion and oxidation, making them suitable for minting currency.

2. **Identifying the Group of Coinage Metals:**
- Coinage metals belong to a specific group in the periodic table. They are found in Group 11 of the periodic table.

3. **Listing the Coinage Metals:**
- The primary examples of coinage metals are:
- Copper (Cu)
- Silver (Ag)
- Gold (Au)
- These metals are not only used for coins but also for jewelry and other decorative items due to their attractive appearance and properties.

4. **Classifying Coinage Metals:**
- Coinage metals are classified as transition metals. Transition metals are elements that have partially filled d-orbitals and exhibit unique properties, including variable oxidation states and the ability to form colored compounds.

5. **Evaluating the Options:**
- Given the options:
1. Normal metals
2. Transition metals
3. Active metals
4. Highly electropositive
- The correct classification for coinage metals is "Transition metals," as they fit the criteria of being in Group 11 and possessing the characteristics of transition metals.

6. **Conclusion:**
- Therefore, the answer to the question "Coinage metals are" is **Transition metals**.
