Question

What are the effects of lanthanoid contractions

Answer 1

$\huge\bold{Answer}$

Shielding and its Effects on Atomic Radius. The Lanthanide Contraction is the result of a poor shielding effect of the 4f electrons. The shielding effect is described as the phenomenon by which the inner-shell electrons shield the outer-shell electrons so they are not effected by nuclear charge.

Answer 2

Answer:

Explanation:

One of the major effects of lanthanoid contraction which affects the other properties is decrease in atomic size of inner transition elements or lanthanoids. One must not get confused that in many cases the sizes are observed to be constant as we move from left to right in lanthanoid series.
