Actinoid contraction is greater from element to element than lanthanoid contraction ?

Text Solution

Verified by Experts

The decrease in atomic (or ionic) radii in actinoid elements (actinoid contraction) is greater than Ianthanoid contraction because 5f-electrons have poor shielding effect as c0mpared to 4felectrons. Therefore, the effect of increased, nuclear charge leading to contraction in size is more in case of actinoid elements.
