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

Text Solution

Verified by Experts

Though the actinoid contraction is like lanthenoid contraction, this contraction is greater from elemeat to elerient resulting from poor shield. ing by 5 felectrons as compared to 4 f electrons of lanthanoids.
