There is a greater range of variable oxidation states among the actinoids than among the lanthanoids, Why ?

Text Solution

Verified by Experts

In actinoids, there is less energy difference in the 5f, 6d and 7s orbitals as compared to 4f, 5d and 6s orbitals in case of lanthanoids. This means that more electrons are available for bonding in actinoids as compared to the members of lanthanoids family.
