Where Is the Smallest Subatomic Particle?

Quarks. Quarks represent the smallest known subatomic particles. These building blocks of matter are considered the new elementary particles, replacing protons, neutrons and electrons as the fundamental particles of the universe. There are six types, called flavors of quarks: up, down, charm, strange, top and bottom.

Which subatomic particle is the smallest?

The smallest particle is the quark, the basic building block of hadrons. There are two types of hadrons: baryons (three quarks) and mesons (one quark, one antiquark).

Which has the smallest particle?

Quarks are the smallest particles we have come across in our scientific endeavor. The Discovery of quarks meant that protons and neutrons weren't fundamental anymore.
