Fe (iron) has 26 protons, 30 neutrons and 26 electrons. In order to calculate the binding energy, first you need to find the total mass of all particles in the nucleus:

26 x mass of proton + 30 x mass of neutron (all in a. m. u.) = say "m"

Mass defect is m - 55.9207 amu, then convert it into grams and put in equation E = mc2 to get binding energy of Fe.

Divide it by number of nucleons to get binding energy per nucleon.
