The unstable nuclide is called the parent nuclide; the nuclide that results from the decay is known as the daughter nuclide.

Figure 3 summarizes these types of decay, along with their equations and changes in atomic and mass numbers.

Positron emission tomography (PET) scans use radiation to diagnose and track health conditions and monitor medical treatments by revealing how parts of a patient’s body function (Figure 4).

The loss of an inner shell electron leaves a vacancy that will be filled by one of the outer electrons.

As the outer electron drops into the vacancy, it will emit energy.

Electron capture occurs when one of the inner electrons in an atom is captured by the atom’s nucleus.

For example, potassium-40 undergoes electron capture: Electron capture occurs when an inner shell electron combines with a proton and is converted into a neutron.

We classify different types of radioactive decay by the radiation produced. Alpha particles, which are attracted to the negative plate and deflected by a relatively small amount, must be positively charged and relatively massive.

Beta particles, which are attracted to the positive plate and deflected a relatively large amount, must be negatively charged and relatively light.

Although the radioactive decay of a nucleus is too small to see with the naked eye, we can indirectly view radioactive decay in an environment called a cloud chamber.
