Rubidium Valence Electrons
Why rubidium has 1
Rubidium has 37 electrons, arranged as 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s1. The highest shell is n = 5, holding 5s1, so 1.
Rubidium is in group 1, and groups 1 and 2 have as many valence electrons as their group number.
What that means for bonding
As a metal, rubidium tends to lose valence electrons rather than gain them, forming Rb+ ions.
Electrons per shell: 2, 8, 18, 8, 1. See the rubidium electron configuration and orbital diagram or the full rubidium data sheet.
Same group, same count
Rubidium valence electrons FAQ
How many valence electrons does rubidium have?
