Figure shows a diagrammatic representation of the decay of bismuth-211. The equation for the decay of bismuth-211 is as follows: The daughter nuclide has 2 protons less and 2 neutrons less than the parent nuclide. This means that in alpha decay, the proton number is reduced by 2 while the nucleon number is reduced by 4.
