• B. lt belongs to 6th period and group
• C. It belongs to 6th period and 3rd group
• D. None of these

Answer 1

Answer: (D)

None of these

• Lutetium is a chemical element with symbol Lu and atomic number 71 and electronic configuration $\left[Xe\right]4f^{14}5d^{1}6s^2$. It is a silvery white metal, which resists corrosion in dry air, but not in moist air. Lutetium is the last element in the lanthanide series, and it is traditionally counted among the rare earths.
