Question

The correct set of four quantum numbers for valence electrons of rubidium atom (Z=37) is
A. `5,1,1,+(1)/(2)`
B. `5,0,1,+(1)/(2)`
C. `5,0,0,+(1)/(2)`
D. `5,1,0,+(1)/(2)`

Answer 1

Correct Answer - C
Electronic configuration of valence shell of `Rb_(37)` is:
`Rb_(37)to5s^(1)`
`n=5,l=0,m+(l)=0,m_(s)=+(1)/(2)`
