Why do isotope decay
BaLLatris [955]

Instability

Explanation:

Isotopes decays because they are unstable. Stable isotopes do not decay.

  • For every atomic nucleus, there is a specific neutron/proton ratio.
  • This ratio ensure that a nuclide is stable.
  • For example, fluorine F, is 10/9 stable.
  • Any nucleus with a neutron/proton combination different from its stability ratio either too many neutrons or too many protons will become unstable.
  • Such nuclide will split into one or more other nuclei with the emission of small particles of matter and considerable amount of energy.
