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

Multiple Choice Options

  • A 5, 1, 1, + 1/2
  • B 5, 1, 0, + 1/2
  • C 5, 0, 0, + 1/2
  • D 5, 0, 1, + 1/2

Step-by-Step Verified Solution

The electronic configuration of Rubidium (Rb = 37):
1s22s22p63s23p63d104s24p65s1

As you can see last electron or valence electron enterin 5s subshell

So, the quantum numbers are n = 5, ll = 0, m = 0, s = ±12\pm {1 \over 2}
