Question

Why is a heavy nucleus unstable on the basis of forces acting inside the nucleus?​

Answer 1

Answer:

Explanation:

The presence of too many protons and neutrons in heavier nucleus will upset the balance and binding energy of nuclear force, which make the nucleus unstable. Such an unstable nucleus achieves the balance by giving off the neutron and proton via radioactive decay.

Answer 2

Answer:

These things do not occur physically. In fact there has to be a proper proportion between the numbers of neutrons and protons. In heavier nuclides there are fifty percent more neutrons than protons. Thus there are serious flaws with the conventional theory of nuclear structure; i.e., the nuclear strong force.
