Question

Correct set of for quantum numbers for the outermost electron of rubidium (Z = 37).

Answer 1

Actually, the outermost valence electron of rubidium is : 5s¹ for which,

Principal quantum no, (n) = 5

Azimuthal quantum no. (l) = 0 ( l= 0 for s-orbitals)

Magnetic quantum no. (m) = -l to + l = 0

Spin quantum no. = =1/2 or -1/2
