In unstable nuclei the strong nuclear forces do not generate enough binding energy to hold the nucleus together permanently. It is unstable nuclei that are radioactive and are referred to as radioactive nuclei and in the case of their isotopes called radioisotopes.
The unstable nuclei lie above and below the line of stability in the neutron – proton plot. This gives information of the type of radioactive decay they will undergo. Nuclei which lie above the line of stability contain too many neutrons to be stable. They are referred to as “neutron rich”. Those that lie below the line of stability contain too many protons to be stable and are called “proton rich”.
In summary it is the balance of protons and neutrons in a nucleus which determines whether a nucleus will be stable or unstable. Too many neutrons or protons upset this balance disrupting the binding energy from the strong nuclear forces making the nucleus unstable. An unstable nucleus tries to achieve a balanced state by given off a neutron or proton and this is done via radioactive decay

When there is an imbalance in the number of protons and neutrons, the nucleus is said to be unstable.
Explanation:
- Atom is considered as the basic unit of matter.
- It has a nucleus and an orbit.
- The nucleus of the atom is composed of proton and neutron, whereas the electron is seen revolving around the atom's orbit.
- It is the equalization of protons and neutrons in a nucleus which decides about the stability of the nucleus.
- Presence of a large number of neutrons or protons upset this equalization upsetting the coupling vitality from the strong nuclear force and thus making the nucleus unstable.
