Atomic Forces

We know an atom is made up of protons, neutrons, and electrons. But what keeps atoms stable?

Three fundamental forces work together to keep atoms stable.

The first is the electromagnetic force, which attracts or repels all charged particles. This force keeps negatively charged electrons surrounding the positively charged nucleus, stopping them from drifting away.

Next is the strong nuclear force, which acts as the glue that holds protons and neutrons tightly within the nucleus despite the repulsion between protons.

This force works at the level of quarks, the tiny particles that make up protons and neutrons.

Quarks have a special kind of charge called color charge. Every quark can be either red, blue, or green. It isn’t about actual colors but explains how they stick together tightly through strong interactions.

The third force is the weak nuclear force. Unlike the others, it doesn’t hold particles together but transforms them.

For example, this force can change a proton into a neutron by transforming its quarks.

These forces keep atoms stable, forming the building blocks of all matter.
