Which metal has the highest melting point?

Options

A. Pt
B. W
C. Pd
D. Au

Answer

To determine which metal has the highest melting point, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Metals in Question**:
We need to consider the transition metals and other relevant metals to determine which one has the highest melting point.

2. **Understand Transition Metals**:
Transition metals are those found in the d-block of the periodic table. They typically have variable oxidation states and are known for their ability to form strong metallic bonds.

3. **Examine the Melting Points of Transition Metals**:
As we move across the transition metals from Scandium (Sc) to Manganese (Mn), we observe that the melting points generally increase. However, Manganese has a unique electronic configuration (3D5), which makes it particularly stable.

4. **Consider the Trend**:
After Manganese, the melting points of the transition metals tend to decrease. This is due to the nature of metallic bonding and the number of unpaired electrons available for bonding.

5. **Identify Other Metals**:
Beyond transition metals, we should also consider other metals known for their high melting points, particularly Tungsten (W), which is often noted for having the highest melting point among all metals.

6. **Conclusion**:
Based on the analysis, Tungsten (W) has the highest melting point due to its extremely high bond energy and strong metallic bonding capabilities.

### Final Answer:
Tungsten (W) has the highest melting point among metals.
