WebAnswer (1 of 3): Potassium atom has 19 electons. Electronic configuration includes - 2,8,8,1. According to the octet rule, the atom or ion to be stable has to have 8 electons in the outermost shell. It's practically impossible for the potassium atom to gain 7 electons as compared to losing one... WebSubmit Previous Answers Correct Potassium has an atomic number of 19, which never changes because the identity of an element depends on the atomic number. The number of electrons can change when forming ions, and the number of neutrons can be different (isotopes).
