Fundamental Particles: Definition & Properties

In summary, fundamental particles, also known as elementary particles, are the building blocks of matter and the smallest, indivisible particles in the universe. There are currently 17 known fundamental particles, including 6 quarks, 6 leptons, and 5 bosons. These particles have properties such as mass, charge, and spin, which determine their interactions and the forces acting upon them. Scientists study fundamental particles using particle accelerators and detectors to observe their interactions, as well as theoretical models and mathematical equations to understand their behavior. Fundamental particles are important because they help us understand the nature of matter and the universe, providing insights into the fundamental laws of physics.

Perhaps this question has been addressed before, but, allow me to ask:

What consitutes the classification of a "fundamental" particle?
Does a fundamental particle have ANY half-life? Seems it would not.
Is a fundamental particle completely impervious to destruction?

Fundamental fermions do not decay, but "transform" one on another.

What are fundamental particles?

Fundamental particles, also known as elementary particles, are the building blocks of matter. They are the smallest, indivisible particles that make up everything in the universe.

How many fundamental particles are there?

There are currently 17 known fundamental particles. These include 6 quarks, 6 leptons, and 5 bosons.

What are the properties of fundamental particles?

Fundamental particles have properties such as mass, charge, and spin. These properties determine how they interact with other particles and the forces that act upon them.

Why are fundamental particles important?

Fundamental particles are important because they help us understand the nature of matter and the universe. By studying their properties and interactions, scientists can gain insights into the fundamental laws of physics.

How do scientists study fundamental particles?

Scientists study fundamental particles using particle accelerators, such as the Large Hadron Collider, and detectors to observe their interactions. They also use theoretical models and mathematical equations to understand their behavior.
