Packing fraction and binding energy both decide the stability. Which of the following statements supports it? 

Concept:

Packing fraction:

• It is defined as the mass per unit nucleon.
• Formula, packing fraction = Δ m/A where Δ m = change in mass, A = nucleon
• A negative packing fraction indicates the stability of the nucleus thus, a large binding energy and vice versa.

Binding energy:

• The amount of energy required to separate a particle from a system of particles or to disperse all the particles of the system.
• Binding energy is especially applicable to subatomic particles in atomic nuclei, to electrons bound to nuclei in atoms, and to atoms and ions bound together in crystals.
• Formula, Δ E = Δ mc2 where Δ E = binding energy, Δm = change in mass, c = speed of light

Explanation:

• The packing fraction might be positive, negative, or 0 percent.
• If the packing fraction is more than one, the nucleus is unstable and will undergo fusion or fission, depending on the packing fraction.
• The nuclei are particularly stable if the packing fraction is negative and vice versa. In this scenario, mass defects reveal the presence of binding energy.
