Q. The electronic configuration of actinoids can to be assigned with degree of certainty because of
A) Overlapping of inner orbitals
B) Free movement of electrons over all the orbitals
C) Small energy difference between $5f$ and $6d$ levels
D) None of the above
Explanation
(c)
There is very small difference in energies of $5f,\ 6d$ and $7s$ orbitals of actinoids, therefore their electronic configuration cannot assigned with a degree of certainty
