Which of the following is a representative element ?

Options

A. Zn
B. Sr
C. Cu
D. Fe

Answer

To determine which of the given options is a representative element, we need to understand the classification of elements in the periodic table.

### Step-by-Step Solution:

1. **Understand the Periodic Table Structure**:
- The periodic table is organized into groups (vertical columns) and periods (horizontal rows).
- Groups contain elements with similar chemical properties.

2. **Identify Representative Elements**:
- Representative elements are found in the S and P blocks of the periodic table.
- The S block includes Group 1 (alkali metals) and Group 2 (alkaline earth metals).
- The P block includes Groups 13 to 18.

3. **Identify Transition Metals**:
- Transition metals are located in the D block, which corresponds to Groups 3 to 12 of the periodic table.

4. **Analyze the Given Options**:
- Look at the options provided in the question.
- Identify which of these options falls under the S or P block (representative elements) and which fall under the D block (transition metals).

5. **Select the Representative Element**:
- For example, if the options include elements like Zinc, Strontium, Copper, and Iron:
- Zinc is a transition metal (D block).
- Strontium is an alkaline earth metal (Group 2, S block).
- Copper is a transition metal (D block).
- Iron is a transition metal (D block).
- From this analysis, Strontium is the representative element.

### Conclusion:
The representative element among the options is **Strontium**.
