Photographic Print

Visualisation of a silicon nucleus This image represents the nucleus of a silicon atom The nucleus is made of particles called nucleons protons and neutrons Each nucleon is composed of three quarks surrounded by a quantum cloud of virtual particles Protons have two up quarks and one down quark neutrons have two down and one up The nucleons are bound together by the strong nuclear force the same force which binds the quarks together within each nucleon The colours in the image reflect the three charges of the strong force known as red green and blue Each nucleon has one quark of each colour charge
