Question

Choose the option which shows common feature in the relationship given in each question.
Chlorine Fluorine: Iodine

• A. These are names of inert gases
• B. These are gases at room temperature
• C. These are transition elements
• D. These are halogens

Hint:

Chlorine Fluorine: Iodine

Answer 1

The Correct Option is D

To determine the common feature in the relationship between "Chlorine Fluorine" and "Iodine," we need to analyze the given options:

1. These are names of inert gases: Chlorine, Fluorine, and Iodine are not inert gases. Inert gases are noble gases like Helium, Neon, Argon, etc. This option is incorrect.
2. These are gases at room temperature: Fluorine and Chlorine are gases at room temperature, but Iodine is a solid. This option does not fit all the elements mentioned. Hence, it's incorrect.
3. These are transition elements: Transition elements are metals found in the center block of the periodic table, such as Iron and Copper. Chlorine, Fluorine, and Iodine are nonmetals and do not fit in this category. Therefore, this is not the correct option.
4. These are halogens: Chlorine, Fluorine, and Iodine are all part of Group 17 (Group VIIA) in the periodic table, known as the halogens. Halogens are characterized by having seven valence electrons and are highly reactive non-metals. This option accurately describes the relationship.

Conclusion: The correct answer is the option stating that these elements are halogens, as all the given elements belong to the halogen group in the periodic table.
