Causes of Lanthanide Contraction

Inner Transition Elements (f – block) – Lanthanoids

Lanthanides: Lanthanides consist of elements that follow lanthanum and involve the filling of 4f subshell. Electronic Configuration: [Xe] 4fn+1 5d° 6s2 or [Xe] 4fn 5d1 6s2 The general valence shell electronic configuration of lanthanides is 4f1−146s2. Atomic and Ionic Sizes of Lanthanides: Atomic and ionic radii of lanthanides decrease with an increase in atomic number. This gradual decrease is known as lanthanides contraction.
