Actinoid contraction is greater from element to element than lanthanoi – InterviewSolution

1.	Actinoid contraction is greater from element to element than lanthanoid contraction. why?
Answer» Solution : The decrease in atomic radii in actinoid ELEMENTS is GREATER than lanthanoid contraction because 5f electrons have poor shielding effect as COMPARED to 4f electrons. Therefore, the effect of increased NUCLEAR CHARGE leading to contraction in size is more in case of actinoid elements.
