Choose an option
Show full solutionCorrect option: C
Correct answer
C5, 0, 0, + 1/2
Step-by-step explanation
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, = 0, m = 0, s =
1s22s22p63s23p63d104s24p65s1
As you can see last electron or valence electron enterin 5s subshell
So, the quantum numbers are n = 5, = 0, m = 0, s =
