What is a gluon? |
A subatomic particle that acts as a mediator to hold the nucleus together. The particle is a quark known as a gluon. |

|
It is theorized that protons and neutrons are actually formed from a combination of smaller particles. What are these particles called? |
A neutron is made of three quarks, and is a baryon (baryons are a type of hadron). The colors used do not matter; just which quarks are there. A quark is a tiny particle which makes up protons and neutrons. Atoms are made of neutrons, protons, and electrons. |
