Example 2
mediumExplain why neutrons are important for nuclear stability. Why do heavier elements tend to have more neutrons than protons?
Solution
- 1 Protons are positively charged and repel each other via the electromagnetic force.
- 2 Neutrons provide the strong nuclear force that binds nucleons together without adding electrostatic repulsion.
- 3 In heavier elements, more neutrons are needed to overcome the increasing proton-proton repulsion, so the neutron-to-proton ratio increases.
Answer
The balance between the strong nuclear force (attractive) and electromagnetic repulsion determines nuclear stability. This is why isotopes with too many or too few neutrons are often radioactive.
About Neutron
A neutral subatomic particle found in the nucleus of an atom that has no electric charge but contributes to the atom's mass.
