Actinoids in general show more oxidation states than the lanthanoids. 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.
Answer
(B) lower energy difference between 5 f and 6 d orbitals than between 4 f and 5 d orbitals
