According to the standard model of particles that is most commonly accepted today, there are three main catagories of particle:
Hadrons - these are heavy particles that are made up of a combination of three quarks. The most common are protons (made of 2 up quarks and a down quark), neutrons (2 downs and an up), anti-protons (2 anti-ups and an anti-down) and anti-neutrons (2 anti-downs and an anti-up).
Leptons - these are light particles that as far as anyone knows do not consist of lower building blocks. examples of these include electrons, positrons, muons, and neutrinos and their anti-counterparts.
Mesons - these particles made up of 2 quarks. There are 2 main types of meson, the pi meson and the k meson. Each meson is made of a quark and an anti quark. Pi mesons do not have strangeness, but K mesons do.

The building block of all matter...
An atom is a fundamental building block of matter. It consists of a nucleus composed of protons and neutrons, surrounded by electrons in orbit. Atoms combine to form molecules, which make up all substances found in the universe.
An Atom. Molecules are two or more atoms chemically combined. Atoms are the basic building block of matter.
