The correct set of four quantum numbers for the valence electron of rubidium atom (Z=37) is

Options

  1. A5,1,1,+ 1 2
  2. B6,0,0,+ 1 2
  3. C5,0,0,+ 1 2
  4. D5,1,0,+ 1 2

Correct answer

C. 5,0,0,+ 1 2

Step-by-step solution

₃₇ Rb = ₃₆[ Kr ] 5 s^1 Its valence electron is 5 s^1 . So, aligned & n =5 & l =0 (For s orbital) & m =0 ( As m=-l to +l) & s =+ 1 2 aligned
