Binding energy is the energy required to disassemble a whole system into separate parts. A bound system typically has a lower potential energy than the sum of its constituent parts; this is what keeps the system together. Often this means that energy is released upon the creation of a bound state. This definition corresponds to a positive binding energy.
Q2. (a) In the context of an atomic nucleus, (i) state what is meant by binding energy, and explain how it arises, The binding energy of a nucleus is the energy needed to separate the nucleus into its constituent nucleons.ii) state what is meant by mass difference, The mass of a nucleus is less that the total mass of its constituent nucleons. Îm-the mass difference is difference between the mass of nucleus and the total mass of the individula nucleons that make it up. Îm = Z m p + (A â Z) m n â m nucleus (max 2).
