The correct Answer is:
To determine the group where electronegativity (EN) increases down the group, we will analyze the general trends of electronegativity in the periodic table and then focus on specific groups to identify any exceptions. ### Step-by-Step Solution: 1. **Understanding Electronegativity Trends**: - Electronegativity generally increases from left to right across a period due to increasing nuclear charge. - Conversely, electronegativity typically decreases as you move down a group because the increased distance between the nucleus and the valence electrons reduces the nucleus's ability to attract electrons. 2. **Identifying Groups with Exceptions**: - While the general trend is that electronegativity decreases down a group, there are exceptions in certain groups, particularly among the transition metals. - One notable group is Group 12, which includes the elements zinc (Zn), cadmium (Cd), and mercury (Hg). 3. **Analyzing Group 12 Elements**: - In Group 12, the electronegativity of these elements does not follow the typical trend. Instead, it increases down the group. - This increase can be attributed to the imperfect screening effect of the d and f orbitals, which affects how the nucleus interacts with the valence electrons. 4. **Conclusion**: - Therefore, the group where electronegativity increases down the group is Group 12, which contains zinc, cadmium, and mercury. ### Final Answer: The correct answer is **Group 12** (Zinc, Cadmium, Mercury). ---
