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.

Unstable atomic nuclei decay over time into stable nuclei causing a mineral to be?
radioactive
Nuclei that have an excess of netrons can become stable by emitting what?
Positrons
When are heavy nuclei most stable?
When they contain an excess of neutrons
Which nuclei would be the least stable?
1 proton, 3 neutrons
When can light elements be predicted to have stable nuclei?
When the neutron:proton ratio is 1:1
Does radioactive isotopes have a stable nuclei?
Radioactive isotopes are not stable.
Why do nuclei decay?
To become 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

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.

70 protons, 98 neutrons
