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

Options

A. `5, 0, 0, +1/2`
B. `5, 1, 0, +1/2`
C. `5, 1, 1, +1/2`
D. `5, 0, 1, +1/2`

Answer

1

Explanation

`Z=37`
Rb is in fifth period.
`[Kr]5s^(1)` is its configuration: " " So `n=5, l=0, m=0, s=+1/2` or `-1/2`
