More number of oxidation states are exhibited by the actinoids than by the lanthanoids. The main reason for this is

A

lesser energy difference between 5f and 6d-orbitals than that between 4f and 5d-orbitals

B

greater metallic character of the lanthanoids than that of the corresponding actinoids

C

more active nature of the actinoids

D

more energy difference between 5f and 6d-orbitals than that between 4f and 5d-orbitals

Text Solution

Verified by Experts

The correct Answer is:
A
The energy difference between Sfand 6d-orbitals is less than that between 4f and 5d-orbitals. Therefore, actinoids (having valence elecrons in 5f and 6d) exhibit more number of oxidation states.
