Neutron-poor nuclides with atomic numbers less than 83 tend to decay by either electron capture or positron emission.

The larger the binding energy, the more stable the nucleus.

The binding energy can also be viewed as the amount of energy it would take to rip the nucleus apart to form isolated neutrons and protons.

Many of these nuclides decay by both routes, but positron emission is more often observed in the lighter nuclides, such as A third mode of decay is observed in neutron-poor nuclides that have atomic numbers larger than 83.

Although it is not obvious at first, -decay increases the ratio of neutrons to protons.

It is therefore literally the energy that binds together the neutrons and protons in the nucleus.

This calculation helps us understand the fascination of nuclear reactions.

Most of the time, the -ray is emitted within 10Nuclides with atomic numbers of 90 or more undergo a form of radioactive decay known as spontaneous fission in which the parent nucleus splits into a pair of smaller nuclei.
