Nuclei are made of protons (positively charged), plus neutrons (no charge)

Positively charged particles repel each other, so there must be another force preventing them from flying apart. That's why there must be an attractive force.

When are heavy nuclei most stable?

Heavy nuclei are most stable when their neutron-to-proton ratio approaches 1. Nuclei with too many or too few neutrons compared to protons will have higher instability. This balance contributes to stability by preventing the repulsion between protons from overpowering the attractive nuclear force.


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.


Attractive force stable nuclei?

It might be because, if the number of electrons are diminished then the number of protons might make the element a highly positively charged element (positive ion)!


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.


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.


Why do electrons stay mostly between the two nuclei?

Electrons stay mostly between two nuclei due to the attractive forces from the positive nucleus and the repulsive forces between electrons. This balance minimizes the total energy of the electron in the system, leading to a stable configuration with the electrons located in the space between nuclei.


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.
