Answer by ab initio in silico for Relativistic effects and lanthanide...
Only orbitals with l=0 (s orbitals) have radial components that are non-zero at the nucleus:s-shells, including and inparticular the 6s shell, are much more sensitive to the relativistic effects...

The lanthanide contraction is caused by two effectsThe 4f orbitals are very diffuse and therefore result in poor screening of the electrons further out, those in the n=5 and n=6 orbitalsrelativistic...

So I understand than the lanthanide contraction is due to poor shielding of the 4f electrons which decreases the radius. However, if Im not mistaken the relativistic effects lead to a contraction of...
