The Band of Stability Predicts Decay Mode
Captions available
The idea
Plotting neutron against proton count for known nuclides traces a narrow band of stability; a nuclide's position relative to it predicts its decay mode.
In practice
Lighter stable nuclides cluster near a 1:1 ratio; heavier ones need progressively more neutrons than protons.
Where people slip
Mistaking the band for an explanation of instability, rather than an empirical predictor of decay mode, is the error.
