The actinoids exhibit more number of oxidation states in general than the lanthanoids. This is because

A

the 5f orbitals extend further from the nucleus than the 4f orbitals

B

the 5f orbitals are more buried than the 4f orbitals

C

there is a similarity between 4f and 5f orbitals in their angular part of the wave function

D

the actinoids are more reactive than the lanthanoids.

Text Solution

Verified by Experts

The correct Answer is:
A
More the disatance between nucleus and outer orbitals, lesser will be force of attration on them . Distance between 4f orbital and nucleus.
So actinoieds exhibit more number of oxidation states in gerneral than the lanthnoids.
