NEETChemistryStructure of AtomMCQ+4 / −1
The correct set of four quantum numbers for the valence electron of rubidium atom (Z = 37) is
- A5, 1, 1, + 1/2
- B6, 0, 0, +1/2
- C5, 0, 0, +1/2
- D5, 1, 0, +1/2

Correct answer: C
Rb(37) = 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1
For 5s, n= 5, l = 0, m = 0, s = +1/2 or -1/2
