. The electronic configuration of actinides cannot be assigned with degree of certaintry because of


a. small energy difference between 5f and 6d levels

b. overlapping of inner orbitals

c. free movement of electrons over all the orbitals

d. All of the above

Best Answer

Answer||| (a)             

Solution ||| Since, there is a very small difference between the energies of 5f and 6d levels, thus the electron can go to 6d level or can remain in 5f level. Hence, the electronic configuration of actinides cannot be assigned with degree of certainty.
