Answer:

We now know that atoms are made up of three particles: protons, neutrons and electrons — which are composed of even smaller particles, such as quarks. Atoms were created after the Big Bang 13.7 billion years ago. ... Quarks came together to form protons and neutrons, and these particles combined into nuclei.
