Solution: Nuclei above the belt of stability can lower their neutron-to-proton ratio through which process?A. alpha decay B. beta emission C. gamma emission D. positron emission E. electron capture

Problem

Nuclei above the belt of stability can lower their neutron-to-proton ratio through which
process?

A. alpha decay
B. beta emission
C. gamma emission
D. positron emission
E. electron capture

Solution

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.
