What is meant by the term "fundamental particle"?

Short Answer

Expert verified
A 'fundamental particle' is a particle that cannot be broken down into smaller particles. They are basically classified into fermions and bosons.

Step by step solution

01

Definition

The term 'fundamental particle' refers to a particle that is not made up of any smaller particles. Fundamental particles are considered the basic building blocks of matter.
02

Classification

In particle physics, fundamental particles are basically classified into two categories: fermions and bosons. Fermions include quarks and leptons, while bosons are force-carrying particles such as photons, gluons, and W and Z bosons.
03

Examples

For instance, an electron is one type of fundamental particle because it is not made up of any smaller particles. Similarly, quarks are also considered fundamental particles as they cannot be further divided.
