STANDARD Chemistry Oxidation States MCQ Question
Type: MCQ-conceptual-Medium
Actinoids in general show more oxidation states than the lanthanoids. The main reason for this is
A
higher energy difference between 5f and 6d orbitals than between 4f and 5d orbitals
B
lower energy difference between 5f and 6d orbitals than between 4f and 5d orbitals
C
higher reactivity of actinoids than lanthanoids
D
actinoids are more basic than lanthanoids.
Correct Answer
Option B
Detailed Explanation
The lower energy difference between 5f and 6d orbitals allows actinoids to exhibit a greater variety of oxidation states compared to lanthanoids.
