K-
A potassium atom has 19 protons and 19 electrons. This is because the number of protons in an atom is equal to its atomic number, which for potassium is 19. Electrons in a neutral atom are equal to the number of protons.
it has 19 electrons and 19 protons and 20 neutrons

19 electrons, 19 protons and 20 neutrons
An electric-neutral K atom has 19 protons and 19 electrons.
19 protons 19 electrons 20 neutrons
A potassium atom has 19 protons and 19 electrons. The number of protons always equals the number of electrons in an atom, as they balance each other to maintain the atom's overall charge neutral.
Potassium has 19 protons, 19 electrons and 20 neutrons.
Fluorine-19 has 9 protons, 10 neutrons, and 9 electrons.
19 electrons, 19 protons and 20 neutrons
An atom with 19 protons, 20 neutrons, and 19 electrons is potassium-39, an isotope of potassium.
