Elementary Particles Classification and Properties

The video tutorial introduces elementary particles, explaining that they lack an internal structure that can be described. It provides examples like electrons, protons, and neutrons, and discusses the classification of these particles based on mass, charge, interaction, spin, and lifetime. The tutorial aims to provide a foundational understanding of elementary particles and their classification.

What defines an elementary particle?

• A particle that is larger than an atom
