Q.
The element with the electronic configuration $[ Xe ] 4 f ^{14} 5 d ^{1} 6 s ^{2}$ is a
The d-and f-Block Elements
Solution:
The general configuration of atoms of lanthanoid elements have electronic configuration with $6 s ^{2}$ common but with variable occupancy of $4 f$ level. $[ Xe ] 4 f ^{14} 5 d ^{1} 6 s ^{2}$ is the electronic configuration of Lutetium (Lu) which comes under lanthanoid series.
