What is the electron configuration, orbital diagram, and noble gas notation of potassium?
Potassium's atomic number is 19. This means that every atom of potassium has 19 protons in its nucleus. In a neutral atom, the number of protons is equal to the number of electrons. So the electron configuration of potassium will involve 19 electrons.
