Mass Number. An element’s mass number (A) is the sum of the number of protons and the number of neutrons. The small contribution of mass from electrons is disregarded in calculating the mass number. If all nuclei of mass number A were to be allowed to be constructed of A neutrons, then 56 Fe would release the most energy per nucleon, since it has a larger fraction of protons than 62 Ni. However, if nuclei are required to be constructed of only the same number of protons and neutrons that they contain, then nickel-62 is the most tightly bound nucleus, per nucleon. For Fe, its atomic number is 26 and its mass number is 56. How many neutrons does it have?

Citing this page. If you need to cite this page, you can copy this text: Kenneth Barbalace. Periodic Table of Elements - Iron - Fe. The atomic weight is basically a measurement of the total number of particles in an atom 's nucleus including both protons and neutrons. So the first step is to locate the atomic mass on the periodic table, and round the value to the nearest whole number.
