The stability of atomic nucleus is determined by ratio of
Neutron/electron
Neutron/proton
positron/neutron
electron/proton
توضیح
Stability of an isotope can be determined by calculating the ratio of neutrons to protons present in a nucleus. Elements having atomic number less than 20, mostly have proton and neutron ratio 1:1.
