Atoms are the building blocks of everything around us. Inside the atom is the nucleus, with protons and neutrons. But there are even smaller particles that make up protons and neutrons, called quarks. Everything that scientists know about atoms is part of the Atomic Theory, which originated in ancient Greece, but continues even today.
