Actinoids in general show more oxidation states than the langthanoids. The main reason for this is

Higher energy difference between 5f and 6d orbitals than between 4f and 5d orbitals

Lower energy difference between 5f and 6d orbitals than between 4f and 5d orbitals

Higher reactivity of actinoids than lanthanoids

Actinoids are more basic than lanthanoids

Text Solution

Verified by Experts

The correct answer is:

Due to lesser energy gap between 5f and 6d orbitals a large number of oxidation states are shown by actinoids
