❤.LANTHANIDE CONTRACTION :

The gradual decrease of atomic size from left to right in lanthanides is called "lanthanide contraction".

❤.CONSEQUENCE:

The crystal structure and other properties of these elements become very close and similar.So it become difficult to separate them from a mixture.

Inert pair effect is consequence of Lanthanide contraction.
