there are currently known to be more than 61 subatomic particles. However, it's important to note that subatomic particles are a topic of ongoing research in the field of particle physics, and new discoveries can be made over time.
Last time i checked, the Standard Model of particle physics describes a collection of elementary particles, including quarks, leptons, gauge bosons, and the Higgs boson. These particles combine in various ways to form the matter and forces in the universe. The Standard Model accounts for the most well-known subatomic particles, such as electrons, protons, neutrons, and neutrinos.
Additionally, there are other subatomic particles that have been discovered outside the realm of the Standard Model, such as mesons, baryons, and various resonances. These particles are formed by the combination of quarks and antiquarks.
It's worth noting that the field of particle physics is constantly evolving, and new particles may be discovered through experiments conducted at particle accelerators, such as the Large Hadron Collider (LHC) at CERN. Scientists are actively working to explore the nature of subatomic particles and expand our understanding of the fundamental building blocks of matter.
