We can … WebBecause potassium has 3 isotopes, then we have to calculate for the different atomic weights of the isotopes: Potassium-39 - It has 19 protons and atomic mass is 39. Hence, number of neutrons is 39 - 19 which is 20. Potassium-40 - It has 19 protons and atomic mass is 40. Hence, number of neutrons is 40 - 19 which is 21.
