Actinoids in general show more oxidation states than the lanthanoids. The main reason for this isA. higher energy difference between 5f and 6d orbitals than between 4f and 5d orbitalsB. lower energy difference between 5f and 6d orbitals than between 4f and 5d orbitalsC. higher reactivity of actinoids than lanthanoidsD. actinoids are more basic than lanthanoids.
