Outline any three main features of specific binding energy curve.

Explanation

The main features of specific binding energy curve:
(i) The binding energy per nuclei is partically constant for nuclei of mass number of atoms `(30 lt A lt 170)`.
(ii) The curve has a maximum specific binding energy of about 8.75 MeV for A=56 and has value of 7.6 MeV for A=238.
(iii) The specific binding energy is lower for both light nuclei `(A lt 30)` and heavy nuclei `(A gt 170)`.
