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?
An unstable nucleus can undergo radioactive decay to become more stable. This can involve emitting radiation in the form of alpha particles, beta particles, or gamma rays. The decay process results in a transformation of the nucleus into a different element or isotope.
What is the antonym of stable?
the antonym of stable is unstable
Does too many neutrons determine if an isotope is unstable?
An isotope with too many neutrons can be unstable for example Hydrogen-3 is unstable while hydrogen-1 and 2 are stable. But so can one with too few neutrons, for example lead-204 is unstable while lead-206, 207, and 208 are 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.
When will an unstable nuclide stop emitting radiation?
An unstable nuclide will stop emitting radiation when it decays into a stable daughter nuclide. This decay process continues until a stable configuration is reached, which may take seconds to billions of years depending on the nuclide.
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 stable and unstable nuclei?
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance, leading to radioactive decay.
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 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.
What happens to a nucleus of an unstable atom?
An unstable nucleus can undergo radioactive decay to become more stable. This can involve emitting radiation in the form of alpha particles, beta particles, or gamma rays. The decay process results in a transformation of the nucleus into a different element or isotope.
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 Neptunium and nickel?
Nickel is a natural and stable chemical element, neptunium is an artificial, unstable and radioactive metal.
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 are the various differences between a stable and an unstable nuclei?
The nuclei of a stable radioactive isotope will after been bombarded with a neutron produce a radiation and enormous energy and such reaction will come to an end, while the nuclei of an unstable nuclei will continue to react with little fragment of the neutron continuously (long chain nuclear reaction) until it has attain it stable phase.mind you this reaction with the little fragment of this neutron can last over 10 years.
What causes radioactivity?
Radioactivity is caused by the instability of an atom's nucleus. An unstable nucleus can emit particles or energy in the form of radiation in order to become more stable. This process is known as radioactive decay.
What is the difference between stable and unstable equilibrium in physics?
In physics, stable equilibrium refers to a state where a system returns to its original position after being disturbed, while unstable equilibrium is a state where a system moves further away from its original position when disturbed.
