Question

what what is Lanthanide contraction

Answer 1

The lanthanide contraction is the greater than expected decrease in ionic radii of the elements in the lanthanide series from the atomic number 57 lanthanum to 71 lutetium

Answer 2

❤.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.
