Potassium has 19 protons, 20 neutrons, and 19 electrons.

Potassium protons

  • Protons = atomic number

From the periodic table, find the atomic number of potassium.

Potassium location on periodic table

The atomic number of potassium is 19. Hence, potassium has a total of 19 protons.

Potassium neutrons

  • Neutrons = atomic mass – atomic number
Potassium neutrons

The atomic mass of potassium is 39.0983, so we’ll take the roundup value as 39. And the atomic number of potassium is 19.

Subtract the atomic number (19) from the atomic mass (39). Hence, potassium has a total of 39 – 19 = 20 neutrons.

Potassium electrons

  • Electrons = atomic number
Potassium electrons

The atomic number of potassium is 19. Hence, potassium has a total of 19 electrons.
