Question

how it is that energy released when a heavier element (or nucleus) breaks up into lighter parts (fission) as wll as when two lighter elements combine to form a heavier element . Please explain with example

Answer 1

In Fission: Due to the mass and energy imparted to the nucleus of an atom by an incoming neutron, the nucleus has enough energy to fission and breaks down into two (or more) smaller nuclei and two or three new neutrons which together have less mass than the original nucleus. This missing mass, sometimes known as the mass defect, is changed into energy.
In Fusion: Two or more small, light atoms combine. The protons and neutrons are combined into a new nucleolus, but there are usually more neutrons in the original light atoms than are necessary for the resulting atom, leaving some mass to be harnessed as energy.

Answer 2

Wasn't sure if you wanted an example in large scale or atomically.

Answer 3

srinidhi i think isme binding energy ka concept hai
