Question

The order of magnitude of the binding energy per nucleon in a nucleus is

Answer 1

Binding energy of nucleus is usually of the order of  Mev . I Mev = x10∧6
1 ev =1.60218e-19 joules.

Binding energy is the total binding energy devide by mass number.

 Binding energy usually determines the stability of the nucleas: the higher the binding energy per nucleon the more stable the nucleas.
