|
Small nuclei are more stable than large nuclei
|
|
|
The nucleus size has nothing to do with its stability
|
|
|
None of the above
|
Detailed explanation-1: -Smaller nuclei are usually more stable because the strong force acts over most all of the particles. As the nuclei gets larger, the repulsion between protons is becomes greater than the strong force causing the nuclei break apart.
Detailed explanation-2: -Bigger nuclei are unstable because of presence of large number of like charge particles. Bigger nuclei have very less number of protons which makes them unstable.
Detailed explanation-3: -More nucleons (protons and neutrons) means more strong force, and more neutrons mean more space between the protons, reducing the repulsion. Together, these effects can produce a stable nucleus.
Detailed explanation-4: -Stable nuclei generally have even numbers of both protons and neutrons and a neutron-to-proton ratio of at least 1. Nuclei that contain magic numbers of protons and neutrons are often especially stable. Superheavy elements, with atomic numbers near 126, may even be stable enough to exist in nature.
