WebbProtons and neutrons, the particles that form the nuclei of atoms, might seem to be really tiny.But scientists say that those subatomic particles themselves are made up of something even smaller — particles called … WebbWhat is smaller than the atom? Quark (noun, “KWARK”) Subatomic means “smaller than an atom.” Atoms are made up of protons, neutrons and electrons. Protons and neutrons are made of even smaller particles called quarks. Based on the evidence available today, physicists think that quarks are elementary particles.

WebbFor comparison, a typical proton in the nucleus of a typical atom weighs 938 million electron volts, or 1.67 × 10^-27 kg, he said. Conversely, the largest (in terms of mass) fundamental particle we know of is a particle called a top quark, measuring a whopping 172.5 billion electron volts, according to Lincoln. What is smaller than a quark? WebbA quark is a fundamental particle that is smaller than any measuring instrument we currently have but does that mean there's nothing smaller?
