General electronic configuration of actinoids is (n–2)f 1–14 (n-1)d 0–2 ns 2 .Which of the following actinoids have one electron in 6d orbital?

Question

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
