Other atoms also can undergo radioactive decay according to their neutron: proton ratio. Therefore, these atoms can undergo radioactive decay. If there are too many protons and too many neutrons, the atoms are heavy. These nuclei undergo radioactive decay in order to become stable. An atom can become unstable due to several reasons such as the presence of a high number of protons in the nuclei or a high number of neutrons in the nuclei. Unstable isotopes are atoms having unstable nuclei. Radioactive decay is the process in which unstable isotopes undergo decay through emitting radiation. Key Terms: Half Life, Isotopes, Neutrons, Protons, Radioactive Decay What is the Relationship Between Radioactive Decay and Half Life This is the relationship between radioactive decay and half life. The time taken by a substance to become half of its initial mass through radioactive decay is measured as the half life of that substance. The radioactive decay of a certain substance is measured by a special term known as the half life. However, the final product of radioactive decay is always stable than the initial isotope. The radioactive decay causes an isotope of a particular element to be converted into an isotope of a different element. Therefore, in order to become stable, these isotopes undergo a spontaneous process called radioactive decay. There are certain naturally occurring isotopes that are unstable due to the imbalanced numbers of protons and neutrons they have in their nucleus of atoms.
