Question

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?
A. U (Atomic number. 92)
B. Np (Atomic number. 93)
C. Pu (Atomic number. 94)
D. Am (Atomic number. 95)

Answer 1

Correct Answer - A::B
General electronic configuration of actinoids is `(n-2)f^(1-14)(n-1)d^(0-2)ns^(2)`. U and Np each have one electron in 6d orbital.
