Nucleon facts for kids
In the amazing world of physics and chemistry, a nucleon is a tiny building block found inside the center of an atom. This center is called the nucleus.
Think of an atom like a tiny solar system. The nucleus is like the sun, and the nucleons are like the planets orbiting it. The most common nucleons are protons and neutrons. They are super important because they make up almost all the mass of an atom! Did you know that nucleons themselves are made of even smaller particles called quarks?

What are Nucleons and Their Features?
The Main Types of Nucleons
The two main kinds of nucleons are protons and neutrons. Each one has special features:
- A proton has a positive electric charge. Think of it like a tiny positive magnet.
- A neutron has no electric charge at all. It's neutral, meaning it's neither positive nor negative.
Together, the protons and neutrons in the nucleus give the atom its overall positive charge. This is because neutrons don't add any charge, so only the protons count!
You might have heard of electrons. They are also tiny parts of an atom, but they are NOT nucleons. Why? Because electrons orbit outside the nucleus, not inside it.
There are also antinucleons. These are like the opposite versions of nucleons, called antiparticles. For example, an antiproton is the antiparticle of a proton.
How Does the Strong Force Hold Nucleons Together?
The nucleus of an atom is packed with protons, which are all positively charged. You might think they would push each other away, right? Like trying to push two positive magnets together!
But they don't! There's a super powerful force that holds them tightly together. This force is called the strong force. It's one of the four basic forces in nature, and it's the strongest one! The strong force acts like super glue, keeping the protons and neutrons stuck together in the nucleus. Without it, atoms wouldn't be able to form!
