Show that the minimum energy needed to sepatate a proton from a nucleus with Z protons and N neutrons is
`Delta E=(M_z-1+M_H-M_(Z,N)c^(2))`
where `M_(Z,N)=mass of and atom with Z protons and N neutrons in the nucleus and `M_H=` mass of a hydrogen atom. this energy is known as proton-separation energy.
