subatomisiin

Subatomisiin is a term that refers to entities smaller than an atom. This category encompasses fundamental particles such as electrons, protons, neutrons, and quarks, as well as composite particles like mesons and baryons. The study of these subatomic particles falls under the domain of particle physics.

Atoms themselves are composed of a nucleus containing protons and neutrons, surrounded by electrons. Protons and neutrons are not fundamental but are instead made up of quarks. Electrons, on the other hand, are considered elementary particles, meaning they are not composed of smaller constituents. The Standard Model of particle physics describes the known fundamental particles and their interactions, categorizing them into quarks, leptons, and force-carrying bosons.

Understanding subatomic particles is crucial for comprehending the nature of matter, the forces that govern the universe, and phenomena such as radioactivity and nuclear reactions. Experiments conducted in particle accelerators play a vital role in discovering and studying these elusive components of reality.
