What is the electron configuration for potassium atomic number 19?

Potassium (K) atom has 19 electrons. The full electron configuration of Potassium (K) is 1s22s22p63s23p64s1. The abbreviated form – [Ar]4s1 – means the electron configuration of Argon (Ar), plus one electron in the 4s orbital.

How many electrons does the potassium ion K+ have?

19 electrons
So if you look for potassium (symbol K in the periodic table), you will find that it has the atomic number of 19. This tells you that potassium has 19 protons and – since the number of protons is the same as the number of electrons- also 19 electrons.
