The transition metal present in the alloy gun metal is ______.

Answer

To solve the question regarding the transition metal present in the alloy gun metal, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Alloys**:
- Alloys are metallic compounds made from two or more elements. They can be in the form of a compound or a solid solution.

2. **Identify Gun Metal**:
- Gun metal is a specific type of alloy that is primarily composed of copper, tin, and zinc. It is a type of bronze.

3. **Determine the Composition of Gun Metal**:
- The typical composition of gun metal is approximately:
- Copper (Cu): 88%
- Tin (Sn): 10%
- Zinc (Zn): 2%

4. **Identify Transition Metals**:
- Transition metals are typically defined as the elements found in the d-block of the periodic table. They include metals such as copper, iron, nickel, and zinc.

5. **Analyze the Composition**:
- In the composition of gun metal, the primary transition metal is copper, which constitutes the largest percentage (88%). Although zinc is also a transition metal, it only makes up 2% of the alloy.

6. **Conclude the Answer**:
- Therefore, the transition metal present in the alloy gun metal is **copper**.

### Final Answer:
The transition metal present in the alloy gun metal is **copper**.
