Question

The element with the electronic configuration $\left[Xe\right]4f^{14}5d^{1}6s^2$ is a:

• A. representative element
• B. transition element
• C. actinide element
• D. Lanthanide element

Answer 1

The correct option is D Lanthanide element

The general configuration of atoms of lanthanoid elements have electronic configuration with $6s^2$ common but with variable occupancy of 4f level. $\left[Xe\right]4f^{14}5d^{1}6s^2$ is the electronic configuration of Lutetium (Lu) which comes under lanthanoid series.
