Welcome to our exploration of atomic nuclei! The nucleus contains protons with positive charges and neutrons with no charge. But here's a puzzle: since like charges repel each other, why don't the positively charged protons push each other away and break the nucleus apart? The answer lies in the strong nuclear force! This is an incredibly powerful attractive force that acts between all nucleons - both protons and neutrons. At the extremely short distances within the nucleus, the strong nuclear force is much stronger than the electrostatic repulsion between protons, effectively holding the entire nucleus together. Let's compare these forces! At large distances, the electrostatic repulsion dominates. But as we bring protons closer to nuclear distances, the strong nuclear force becomes much more powerful - about one hundred times stronger than the electrostatic force. This is why the strong force wins and keeps the nucleus intact! Neutrons play a crucial role in nuclear stability! Since neutrons have no electric charge, they don't contribute to electrostatic repulsion between protons. However, they do participate in the strong nuclear force, adding more attractive binding energy to the nucleus. This helps balance out the repulsive forces and makes the nucleus more stable. To summarize: atomic nuclei don't fall apart because the strong nuclear force is much more powerful than electrostatic repulsion at nuclear distances. Neutrons help by adding attractive force without repulsion. This fundamental balance is what keeps all matter stable in our universe!
