The nuclide with the highest binding energy per nucleon is 56Fe (iron-56).
Step-by-step explanation:
The nucleus with the largest binding energy per nucleon is the one with the mass number near 56. According to the provided information, the nuclide 56Fe (iron-56) has the highest binding energy per nucleon. The binding energy per nucleon is calculated by dividing the total binding energy by the number of nucleons in the nucleus.
