Atomic number of a nucleus is Z and atomic mass is M. The number of neutrons is :
Show that the minimum energy needed to separate a proton from a nucleus with Z protons and N neutrons is △E=(Mz−1,N+MH−MZ,n)C2 Where MZ,n= mass of an atom with Z protons and N neutrons in the nucleus and MH= mass of a hydrogen atom. This energy is known as proton-separation energy.
