An amtom undergoes a reaction ant attains a more stable from how do you know is it was chemical or nuclear reaction?
If an atom undergoes a chemical reaction, it involves rearrangement of electrons in the outer shell to form new chemical bonds. On the other hand, if it undergoes a nuclear reaction, it involves changes in the atomic nuclei, resulting in the formation of different elements or isotopes. To determine whether it was a chemical or nuclear reaction, observe whether there are changes in the electron configuration or in the atomic number and mass of the atom.
What combines in groups or three to form nuclear particles?
Protons and neutrons combine in groups of three to form atomic nuclei. Protons have a positive charge and neutrons have no charge; together, they are held together by the strong nuclear force to form stable atomic nuclei.
What do a heavy nuclei need to remain stable?
Heavy nuclei need to have a balanced ratio of protons to neutrons to remain stable. They also need to have the strong nuclear force between nucleons overcome the electrostatic repulsion between protons. Additionally, the nuclei need to have a sufficient binding energy to hold the nucleus together.
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.
What is the difference between the atomic bomb and hydrogen bomb?
The difference between an A-Bomb and H-Bomb is the energy reaction inside them, one of them is nuclear fusion and the other one is nuclear fission. A-Bombs contain a unstable nuclei such as Uranium 235, whiles H-Bombs contain light stable isotopes of hydrogen and sometimes helium. Nuclear fusion is the merging of atoms/particles, whilst nuclear fission is the splitting and break down of a big unstable nuclei.
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.
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 best describes what forms in nuclear fission?
A two smaller, more stable nuclei
What causes the nuclear reaction to keep going once it has started?
The nuclear reaction in nuclear power plants continues because of a self-sustaining chain reaction. In this process, neutrons produced by fission cause further fission in other uranium or plutonium nuclei, releasing more energy and more neutrons. This chain reaction is controlled and moderated by control rods to maintain a stable and controlled release of energy.
What type of reaction happens inside a nuclear power plant?
A nuclear chain reaction nuclear fission
What is used to change a stable isotope into a radioactive one?
A nuclear reaction
Which of the following nuclei is likely to release energy when undergoing nuclear fusion?
Helium-4, because it has a higher binding energy per nucleon compared to the initial nuclei involved in the fusion reaction. This means that the products of the fusion reaction have a higher binding energy per nucleon and are more stable, resulting in the release of energy.
How does nuclear decay contribute to the process of unstable nuclei achieving greater stability?
Nuclear decay is a process where unstable nuclei release energy or particles to become more stable. This helps unstable nuclei achieve greater stability by reducing their excess energy or changing their composition to reach a more balanced state.
What provides the stability that occurs in larger atomic nuclei?
The most stable nuclei are iron and nickel, and that is due to the binding energy per nucleon being greatest in that size of nucleus. As you go to heavier nuclei like uranium for instance, the nucleus gets less stable. (see the related Wikipedia link) Larger atomic nuclei (up to lead) are stable because the repulsive electrostatic force does not decrease with distance as greatly as the strong nuclear force does.
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 definition of a average star?
The point in in a stars evolution during which it maintains a stable nuclear reaction.
