Among the transiton metals of the first series ( leaving zinc which is not considered as a transition metal ), the lowest meltaing point is shown by `"…................"`

Answer

To determine which transition metal among the first series (excluding zinc) has the lowest melting point, we can analyze the melting points of the transition metals in this series.

### Step-by-Step Solution:

1. **Identify the Transition Metals**: The first series of transition metals includes Scandium (Sc), Titanium (Ti), Vanadium (V), Chromium (Cr), Manganese (Mn), Iron (Fe), Cobalt (Co), Nickel (Ni), Copper (Cu), and Zinc (Zn). However, since we are excluding Zinc, we will consider Sc to Cu.

2. **List the Melting Points**: We need to look at the melting points of these metals:
- Scandium (Sc): 1541 °C
- Titanium (Ti): 1668 °C
- Vanadium (V): 1910 °C
- Chromium (Cr): 1907 °C
- Manganese (Mn): 1246 °C
- Iron (Fe): 1538 °C
- Cobalt (Co): 1495 °C
- Nickel (Ni): 1455 °C
- Copper (Cu): 1085 °C
- Zinc (Zn): 419.5 °C (not considered)

3. **Analyze the Melting Points**: From the melting points listed, we can see that Copper (Cu) has a melting point of 1085 °C, which is lower than all the other transition metals listed (excluding Zinc).

4. **Conclusion**: Therefore, among the transition metals of the first series (excluding Zinc), the metal with the lowest melting point is **Copper (Cu)**.

### Final Answer:
The lowest melting point among the transition metals of the first series (excluding zinc) is shown by **Copper (Cu)**.
