Quark

Fundamental constituents of matter in particle physics.

quark particles

In particle physics, quarks are fundamental constituents of matter. They combine to form composite particles called hadrons, the most stable of which are protons and neutrons. There are six types (or "flavors") of quarks: up, down, charm, strange, top, and bottom, each with associated antiquarks.

Quark comes from the Irish word 'cuar' meaning 'cluster'.

Quarks are tiny pieces that make up protons and neutrons, which in turn build atoms – everything around us!
