Question

Particle having major role in binding the nucleus

Answer 1

Since binding energy is responsible for holding the nucleons in the nucleus. Nuclear stability is proportional to the nuclear binding energy. The more the binding energy the greater is the nuclear stability. If we plot binding energy per nucleon in MeV against mass numbers (A) for different nuclei, a curve is obtained.

Answer 2

Subatomic particles having major role in binding the nucleus

Reason behind binding of nucleus:

• The residual strong force holds nuclei together (nuclear force).
• A tiny remnant of the strong interaction that brings quarks together to produce protons and neutrons is the residual strong force.
• Similar to how electromagnetic forces between neutral atoms (like van der Waals forces that act between two inert gas atoms) are much weaker than the electromagnetic forces that hold the parts of the atoms together internally, this force is significantly weaker between neutrons and protons because it is largely neutralised within them (for example, the forces that hold the electrons in an inert gas atom bound to its nucleus).
