The reason for greater range of oxidation states in actinoids is attributed to -

A

actinoid contraction

B

5f, 6d and 7s levels having comparable energies

C

4f and 5f levels being close in energies

D

the radioactive nature of actinoids

Text Solution

Verified by Experts

The correct Answer is:
B

It is due to the low energy difference between the 5f, 6d and 7s - subshell that actinoids form a wide range of oxidation states.
