Potassium-39 is composed of 19 protons, 20 neutrons, and 19 electrons. Potassium-40 is composed of 19 protons, 21 neutrons, and 19 electrons. Traces of K-40 are found in all potassium, and it is the most common radioisotope in the human body. Mass number is the sum of the protons and neutrons in the nucleus of a specific isotope of an atom. Answer and Explanation: {eq}\rm ^{39}_{19}K {/eq} has 19 protons and 20 neutrons. In this video we’ll use the Periodic table and a few simple rules to find the protons, electrons, and neutrons for the element Potassium (K).

p=19. The atomic mass is the sum Z = atomic number = number of protons in the nucleus = number of electrons orbiting the nucleus; A = mass number Potassium K Z=19, A=39 Y Z=39, A= 89 Kids learn about the element potassium and its chemistry including atomic Potassium atoms have 19 electrons and 19 protons with one valence electron in the There are three isotopes of potassium that occur naturally: K-39, 40, and Number of neutrons = Mass number − Atomic number.

39K has 39 - 19 = 20 neutrons. Potassium-39 is composed of 19 protons, 20 neutrons, and 19 electrons. Potassium-40 is composed of 19 protons, 21 neutrons, and 19 electrons.
