In most atoms the protons and neutrons found in the nucleus are held together strongly. The nuclei of these atoms are said to be stable.
However, the neutrons and protons in some atoms are not held together as strongly. These nuclei are unstable and will eventually disintegrate, forming other elements.
Isotopes that are unstable are said to be radioactive and are called radioactive isotopes or radioisotopes.

What happens to a nucleus of an unstable atom?
the unstable nucleus will decay into smaller, stable particles.
What is the difference between a stable and unstable electronic configuration?
Stable electronic configuration is when the valence shell of an element is completely filled (8 electrons) whereas unstable electronic configuration is when the valence shell of an element is not completely filled
When will an unstable nuclide stop emitting radiation?
An unstable nuclide will stop emitting radiation when the forces in the nucleus are balanced, until they become stable.
Why is a larger nucleus not as stable as a smaller nucleus?
A smaller nucleus is generally more stable. Below are some general rules: # (Except for really small nuclei) All stable nuclei contain a number of neutrons that is equal to or greater than the number of protons. # Nuclei with too few or too many neutrons is unstable. # If a nuclei has even numbers of nucleons, it's generally more stable. # Nuclei with "magic numbers" usually tend to be more stable.
Is a solution stable or unstable?
unstable
How is a stable nucleus different to an unstable nucleus?
A stable nucleus is one which will not decay, whereas an unstable nucleus will decay at some point, which cannot be predicted as decay is a random process, by alpha or beta decay.
What is natural transmutation?
Change from unstable to stable nucleus.
What is the difference between unstable and stable air?
. Unstable air, if lifted, will rise by itself without any forcing. Stable air, if lifted, will tend to sink back down.,
What happens to a nucleus of an unstable atom?
the unstable nucleus will decay into smaller, stable particles.
What would happened to a stable nucleus in which the number of neutrons suddenly decreased?
The nucleus would become unstable because you need a certain amount of neutrons, electrons, and protons for it to be stable.
Was the neutron stable?
An isolated neutron is unstable, so an isolated antineutron is also unstable. A neutron inside a nucleus is stable, so a antineutron inside an antinucleus is also stable.
Is radius caused by stable or unstable nucleus of atoms?
all nuclei, both stable and unstable, have a radius. although the exact size can be hard to define, due to quantum properties.
What is the difference between a stable and unstable electronic configuration?
Stable electronic configuration is when the valence shell of an element is completely filled (8 electrons) whereas unstable electronic configuration is when the valence shell of an element is not completely filled
What is the difference between Neptunium and nickel?
Nickel is a natural and stable chemical element, neptunium is an artificial, unstable and radioactive metal.
When will an unstable nuclide stop emitting radiation?
An unstable nuclide will stop emitting radiation when the forces in the nucleus are balanced, until they become stable.
What is the difference between radioactive and non-radioactive isotope?
Radioactive minerals are unstable and emit radiation at a constant rate. They also have half lives and lose energy overtime. Nonradioactive minerals are stable, and by there own are incapable of emitting energy.
What happens during radioactive decay apex?
An unstable nucleus loses particles until it becomes stable.
