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. Lanthanides element

Answer 1

The correct option is D Lanthanides element

Lutetium $\left[Xe\right]4f^{14}5d^{1}6s^2$ is a lanthanide element as it follows the general configuration for lanthanides: $(n-2)f^{1-14}(n-1)d^{1}n{s}^2$
