The stability of a nucleus in an atom how firmly the particles are held together. Protons in a nucleus would repel each other, but with the help of neutrons, most of the mass of an atom is strongly kept in place.

What are the key differences between stable and unstable nuclei?

Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance. Unstable nuclei undergo radioactive decay to become more stable.


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.


Does radioactive isotopes have a stable nuclei?

Radioactive isotopes are not stable.


Are the nuclei of final elements produced by nuclear decay more stable or less stable than the nuclei of original radioactive elements?

Of course they are more stable, therefore they formed naturally.


Which are more stable nuclei that have an even number of nucleons or nuclei that have an odd number of nucleons?

even

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.


Suppose the pennies represent nuclei of radioactive element what would the heads and tail represent?

In this analogy, the heads of the pennies could represent stable nuclei, while the tails could represent radioactive nuclei. Stable nuclei do not undergo spontaneous decay, while radioactive nuclei have the potential to decay and emit radiation over time.


What Nuclei would be stable?

70 protons, 98 neutrons


Nuclei that have an excess of netrons can become stable by emitting what?

Nuclei that have an excess of neutrons can become stable by emitting beta particles (electrons or positrons). This process helps the nucleus increase its neutron-to-proton ratio and achieve a more stable configuration.


What Nuclei would be most stable?

70 protons, 98 neutrons


Which nuclei would be the least stable?

1 proton, 3 neutrons
