Rubidium | quantum numbers | valence electron | atomic structure | iit jee | neet

Correct set of four quantum numbers for the valence (outermost) electron of Rubidium (Z=37) is :

(IIT JEE 1986)

1) 5, 0, 0, +½

2) 5, 1, 0, +½

3) 5, 1, 1, +½

4) 6, 0, 0, +½

Logic:

We may write the electronic configuration of Rubidium, Rb and then find out the quantum numbers for the last electron.

Rubidium | quantum numbers | valence electron | atomic structure | iit jee | neet.
