Question

What holds the nucleus together ?

Answer 1

Hint: The atomic nucleus is a small, dense area at the core of an atom made up of protons and neutrons. The nucleus is made up of protons (which are positively charged) and neutrons (which are electrically neutral) particles.

Complete answer:
The electromagnetic field is what causes charged particles to interact. Each proton in a nucleus repels any other proton in the nucleus due to the electromagnetic force's long range. This is an attempt to split the nucleus apart.

The strong nuclear force holds the nucleus together, preventing positive protons from repelling each other in the presence of the nucleus. It is stronger than electrostatic repulsion at very short distances, allowing protons to remain together in a nucleus despite their charges repelling each other. Keep in mind that the nucleus is very small in comparison to the size of an atom.

Note: The strong and electromagnetic forces must be balanced for a nucleus to be stable. As a result, only a limited number of protons and neutrons can be bound into a stable nucleus. There is a break-even point when it comes to the strong force. Physicists have discovered that as nucleons are added up to iron, the nucleus becomes increasingly stable.
