By convention orbitals are filled in the following order.
n = 1, 2, 3, …
ℓ = 0, 1, 2, …
mℓ = …, −2, −1, 0, +1, +2, …
ms =
With this in mind, answer the following question.
Give possible values for the quantum numbers of the valence electrons in an atom of niobium (Nb).
(a) n 01234567
(b) ℓ 012345
(c) mℓ −4−3−2−10+1+2+3+4
