Q26 of 70 Page 109

General electronic configuration of actinoids is (n–2)f1–14 (n-1)d0–2 ns2.Which of the following actinoids have one electron in 6d orbital?

Electronic configurations of all the elements are as follows:


U – [Rn] 5f3 6d1 7s2


Np- [Rn] 5f4 6d1 7s2


Pu-[Rn] 5f6 6d0 7s2


Am-[Rn] 5f7 6d0 7s2


So, only Uranium and Neptunium have 1 electron in 6d orbital
