Question : 73 of 180

Marks: +1, -0

Larger number of oxidation states are exhibited by the actinoides than those by the lanthanoids, the main reason being :-

Lesser energy difference between 5f and 6d than 4f and 5d orbitals
More energy difference between 5f and 6d than between 4f and 5d orbitals
More reactive nature of the actinoids than the lanthanoids
4f orbitals are more diffused than 5forbitals
