Actinoids in general show more oxidation...

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

A

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

B

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

C

greater metallic character of the lanthanides than that of the corresponding actinides

D

more active nature of the actinides.

Text Solution

Verified by Experts

The correct Answer is:
B

more number of oxidation states are exhibited by the actinides than by the corresponding lanthanides due to lesser energy difference between 5f and 6d orbitals than that between 4f and 5d-orbitals.
