Respuesta :
Iron-56(Fe-56) isotope is the most stable and would therefore not release energy by either fusion or fission.
What is iron?
Iron is a silver-gray metal that is lustrous, ductile, and malleable. It may be found in four different crystalline forms. In wet air, iron rusts, but not in dry air. In dilute acids, it dissolves quickly.
Atoms that are stable isotopes do not emit radiation. They are utilized in a wide range of applications, including water and soil management.
The graph is in between the average binding energy per nucleon(Mev) and the number of nucleons in the nucleus.
The energy for the isotopes Iron-56(Fe-56 is less and less energy leads to more stability.
Hence Iron-56(Fe-56) isotope is the most stable and would therefore not release energy by either fusion or fission.
