AIPMT PRELIMS 2006 Chemistry Actinoids MCQ Question
Type: MCQ-conceptual-Medium-Class 12
More number of oxidation states are exhibited by the actinoids than by 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 lanthanoids than that of the corresponding actinoids
D
more active nature of the actinoids
Correct Answer
Option B
Detailed Explanation
The lesser energy difference between 5f and 6d orbitals allows actinoids to exhibit more oxidation states.
