Question

What is lanthanide contraction what are the consequences of that lanthanide contraction?​

Answer 1

Answer:

The Lanthanide Contraction is caused by a poor shielding effect of the 4f electrons. Gd because as atomic number increases, the atomic radius decreases. ... Consequently , the attraction of the nucleus for the electrons in the outermost shell increases with the increase of atomic number, thus size decreases.

❤.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.
