Which of the following elements do not belong to the family indicated ?

Options

A. Cu- Coinage metal
B. Ba- Alkaline earth metal
C. Zn- Alkaline earth metal
D. Xe- Noble gas

Answer

To solve the question of which element does not belong to the indicated family, we will analyze each option provided.

### Step-by-Step Solution:

1. **Identify the Families:**
- The question asks us to identify elements that do not belong to the same family. We need to know the families of the elements provided in the options.

2. **Analyze Each Element:**
- **Copper (Cu):**
- Copper is a coinage metal. Coinage metals are typically found in group 11 of the periodic table, which includes copper, silver, and gold.
- **Conclusion:** Copper belongs to the coinage metal family.

- **Barium (Ba):**
- Barium is an alkaline earth metal. Alkaline earth metals are found in group 2 of the periodic table, which includes beryllium, magnesium, calcium, strontium, and barium.
- **Conclusion:** Barium belongs to the alkaline earth metal family.

- **Zinc (Zn):**
- Zinc is a d-block element, specifically part of the transition metals. It is located in group 12 of the periodic table, which is not classified as an alkaline earth metal.
- **Conclusion:** Zinc does not belong to the alkaline earth metal family.

- **Xenon (Xe):**
- Xenon is a noble gas, which is found in group 18 of the periodic table. Noble gases include helium, neon, argon, krypton, xenon, and radon.
- **Conclusion:** Xenon belongs to the noble gas family.

3. **Determine the Odd Element:**
- From the analysis, we see that:
- Copper belongs to the coinage metals.
- Barium belongs to the alkaline earth metals.
- Zinc does not belong to the alkaline earth metals; it is a d-block element.
- Xenon belongs to the noble gases.
- Therefore, the element that does not belong to the indicated family of alkaline earth metals is **Zinc (Zn)**.

### Final Answer:
The element that does not belong to the alkaline earth metal family is **Zinc (Zn)**.
