What nuclei would be the least stable?
1 proton, 3 neutrons
What nuclei would be the most stable?
10 protons, 12 neutrons
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 do a heavy nuclei need to remain stable?
More neutrons than protons.
What is the difference between a stable and unstable nucleus?
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.
When are heavy nuclei most stable?
When they contain an excess of neutrons
What Nuclei would be stable?
70 protons, 98 neutrons
What nuclei would be the least stable?
1 proton, 3 neutrons
Does radioactive isotopes have a stable nuclei?
Radioactive isotopes are not stable.
Why do nuclei decay?
To become stable
What nuclei would be the most stable?
10 protons, 12 neutrons
Most stable types of nuclei have an number of protons and an number of neutrons?
4 protons and 4 neutrons
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
Unstable atomic nuclei decay over time into stable nuclei causing a mineral to be?
radioactive
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.
Why is a larger nucleus not as stable as a smaller nucleus?
