The Valley, Band or Belt of Stability represents the area where stable, non-radioactive isotopes exist based on their ratio of neutrons to protons.
A diagram showing the belt of stability is shown below:
We can see that the type of decay that occurs above the belt is either Beta-decay or emission or Neutron emission.
Nuclei above the belt of stability can lower their neutron-to-proton ratio through which
A. alpha decay
B. beta emission
C. gamma emission
D. positron emission
E. electron capture
