Potassium (chemical symbol K) has 19 each of protons and electrons, because it has an atomic number of 19. Potassium has more than one naturally occuring isotope. Potassium can have an atomic mass of 39, 40, or 41. However, over 90% of naturally occuring Potassium is K-39, with 20 neutrons. K-41, with 22 neutrons, is also stable. K-40 has 21 neutrons, and does occur in nature, but with an abundance of only 0.012%. In addition, it is not truly stable, although its half-life is over a billion years.

The chemical symbol for potassium is "K".
Its atomic number is 19, which means it has 19 proton and 19 electrons. The average atomic mass is 39.0983. The most sable isotope has an atomic mass of 39 and has 20 neutrons.

19 protons and electrons, and 20 neutrons for an atomic mass of 39 in the most common isotope.
