The fundamental components of atoms, including electrons, protons, and neutrons, their properties, and the experiments that led to their discovery, such as the discovery of cathode rays, anode rays, and neutrons, and the determination of their charges and masses
Summary
Subatomic particles are the essential components of atoms, which are the building blocks of all matter. Understanding these particles—protons, neutrons, and electrons—helps us grasp the fundamental principles of chemistry and physics. Protons and neutrons reside in the nucleus, while electrons orbit around it, influencing chemical behavior and reactions. Additionally, quarks, which make up protons and neutrons, reveal deeper layers of matter's structure. The study of subatomic particles is crucial for advancements in technology, such as nuclear energy and medical imaging, and forms the basis for many scientific fields, including particle physics and quantum mechanics.
