About the Particles Zone

All matter is made up of particles, and there are many types of particle. There are atoms which in themselves are incredibly small. An atom contains protons, neutrons, and electrons; which are also particles.

Protons, and neutrons are made of quarks, now we’re looking at very small particles indeed; a quark is smaller than 10-19 m across (that’s just 0.000 000 000 000 000 000 1 m). Quarks are subatomic particles, which also include leptons and bosons — we’ve all heard of the Higgs boson.
