Q. More number of oxidation state are exhibited by the actinoids than by lanthanoids. The main reason for this is :
COMEDK
COMEDK 2015
The d-and f-Block Elements
A
greater metallic character of lanthanoids than that of their corresponding actinoids
7%
B
more active nature of actinoids
8%
C
more energy difference between $5f$ and $6d$ orbitals than that between $4f$ and $5d$ orbitals
33%
D
lesser energy difference between $5f$ and $6d$ orbitals than that between $4f$ and $5d$ orbitals.
52%
Solution:
More number of oxidation states are exhibited by the actinides than by the lanthanides due to lesser energy difference between $5f$ and $6d$ orbitals than that between $4f$ and $5d$-orbitals.
