There is only one stable potassium ion, #K^+#


The cation #K^+# is formed when an atom of potassium loses its single valence electron (a #4s#-electron). This process requires very little energy (the ionization energy of potassium is relatively low), and so the element is readily oxidized (it is a strong reducing agent).
