WebTo find the number of protons in iron iron, first locate the element on the periodic table. Next, find the atomic number which is located above the element 's symbol. Since iron iron 's atomic number is 26 26, Fe Fe has 26 26 protons. 26 26 protons. Fill in the known values where N N represents the number of neutrons. 56 = 26+ N 56 = 26 + N. WebThe number of neutrons in the isotope can be calculated from its mass number, which is written as a superscript in a nuclear symbol. Mass Number = # of Protons + # of Neutrons 40 = 19 + # of Neutrons 40 - 19 = # of Neutrons Therefore, there are 21 neutrons in this isotope of potassium (K).
