Rubidium has one 5s electron.
5s
Ruthenium has a electron configuration of *[Kr]4d^7 5s^1. It has only one valence electron. Ruthenium is a rare transition metal that belongs with the platinum group on the periodic table.
Sb has 5 valence electrons, In has 3, Rb has 1 valence electron and Xe has 8. So in ranking, it would be, Xe, Sb, In, Rb.
For group 1 elements : lithium , sodium, potassium...etc All of them have one valence electrons , however Rubidium(Rb) have two valence electrons. Therefore, Cesium have one valence electrons. :D
Fluorine require only one electron to fill its outer shell. Hence it has the greatest tendency to gain electrons than Al, Rb and I.
5s
Rubidium has one valence electron in the 5s orbital.
Rubidium (Rb) has a +1 ion, will have the same electron configuration as krypton (Kr) because the +1 status means it has lost an electron. The configuration is written 1s22s22p63s23p64s23d104p6.

This alkali metal is Rubidium Rb, having atomic no 37

There is actually 37 Protons in Rb (Rubidium). Also there is the same number of protons as electrons. So 37 for protons and electrons. (: Your welcome little kid.
