Binding Energy in Nuclear Physics

Atomic Nucleus stability is discussed in terms of its Binding Energy (BE). New insights in understanding many Nucleus properties like limit of stability are obtained. BE generalized to the structured objects give some hints to find origin of the missing mass (dark matter). The very new CHAIN Model of the nucleus is confronted with the classical mass formula. Some ideas for studies of Super Heavy Elements (SHE) related to the role of high spin states and their importance in binding energy calculation are presented.
