Fundamental particles are the basic building blocks of matter and are classified into two categories: elementary particles and composite particles. Elementary particles are indivisible and do not have any substructure, while composite particles are made up of combinations of elementary particles. Here are some properties of fundamental particles: 1. Mass: Mass is a fundamental property of particles and represents the amount of matter in a particle. It is usually measured in units such as kilograms or electron volts (eV). Different particles have different masses, ranging from extremely small (like neutrinos) to relatively large (like the top quark). 2. Charge: Charge is a fundamental property of particles that determines their electromagnetic interactions. Particles can have positive, negative, or zero charge. For example, electrons have a negative charge, protons have a positive charge, and neutrons have zero charge. 3. Spin: Spin is an intrinsic property of particles and is related t...
