The reason is the same as for atomic radii: shielding by filled inner shells produces little change in the effective nuclear charge felt by the outermost electrons.
WebThe ionic radii of the lanthanides decrease from 103 pm (La 3+) to 86 pm (Lu 3+) in the lanthanide series, as electrons are added to the 4f shell. This first f shell is inside the full 5s and 5p shells (as well as the 6s shell in the neutral atom); the 4f shell is well-localized near the atomic nucleus and has little effect on chemical bonding.
