NEET Chemistry QUESTION #7420
Question 1
Element with atomic number Z = 114 would belong to which group and have which electronic configuration?
  • Carbon family, [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p²✔️
  • Oxygen family, [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁴
  • Nitrogen family, [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁶
  • Halogen family, [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁵
Correct Answer Explanation
Finding the position of Z=114 (Flerovium, Fl):
After Rn (Z=86): fill 7s² (88), 5f¹⁴ (102), 6d¹⁰ (112), then 7p²...
Z=113: 7p¹ (Group 13), Z=114: 7p² (Group 14 = Carbon family)

Configuration: [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p² ✓

Flerovium (Fl, Z=114) is in Group 14, Period 7, homologue of Pb.
