WebMain Isotopes of Potassium. There are 25 known isotopes of potassium, three of which occur naturally: 39K (93.3%), 40K (0.0117%), and 41K (6.7%). 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 ... WebExample #5: In a sample of 400 lithium atoms, it is found this 30 atoms are lithium-6 (6.015 g/mol) and 370 atoms are lithium-7 (7.016 g/mol). Calculate the average nuclear measure of lithium. Solution: 1) Calculate the percent overload for each isotope: Li-6: 30/400 = 0.075 Li-7: 370/400 = 0.925. 2) Calculate the average atomic weight:
