If the total binding energies of ₁² H , ₂⁴ He , ₂₆⁵⁶ Fe & ₉₂²³⁵ U nuclei are 2.22,28.3,492 and 1786 MeV respectively, identify the most stable nucleus of the following.

Step-by-step solution

aligned B.E _ H &= 2.22 2 =1.11 B.E _ He &= 28.3 4 =7.08 B.E _ Fe &= 492 56 =8.78= maximum B.E _ U &= 1786 235 =7.6 aligned 56 26 Fe is most stable as it has maximum binding energy per nucleon.
