Potassium Valence Electrons
Why potassium has 1
Potassium has 19 electrons, arranged as 1s2 2s2 2p6 3s2 3p6 4s1. The highest shell is n = 4, holding 4s1, so 1.
Potassium 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, potassium tends to lose valence electrons rather than gain them, forming K+ ions.
Electrons per shell: 2, 8, 8, 1. See the potassium electron configuration and orbital diagram or the full potassium data sheet.
Same group, same count
Potassium valence electrons FAQ
