Text Solution
Verified by ExpertsThe correct answer is:
D
Actinides show different oxidation states such as +2, +3, +4, +5, +6 and +7 . However +3 oxidation state is most common among all the lanthanides.The wide range of oxidation states of actinides is attributed to the fact that the 5f ,6d and 7s energy levels are of comparable energies. Therefore all these three subshells can participate.
