In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. [1] The Standard Model presently recognizes seventeen distinct particles—twelve fermions and five bosons .

2022年9月20日 · Elementary particles are the smallest known building blocks of the universe. They are thought to have no internal structure, meaning that researchers think about them as zero-dimensional points...

2025年1月20日 · The term subatomic particle refers both to the true elementary particles, such as quarks and electrons, and to the larger particles that quarks form. Although both are elementary particles, electrons and quarks differ in several respects.

In physics, an elementary particle or fundamental particle is a particle that is not made of other particles. An elementary particle can be one of two groups: a fermion or a boson . Fermions are the building blocks of matter and have mass, while bosons behave as force carriers for relations between fermion and some of them have no mass. [ 1 ]

Elementary particles are also called fundamental particles and have no other smaller particles within them. These particles generate every matter in the universe though not composed of any other particles.

All matter around us is made of elementary particles, the building blocks of matter. These particles occur in two basic types called quarks and leptons. Each group consists of six particles, which are related in pairs, or “generations”.

Elementary particle physics is the study of fundamental particles and their interactions in nature. Those who study elementary particle physics—the particle physicists—differ from other physicists in the scale of the systems that they study.

A review of the elementary particles for A Level physics. Covers the properties and roles of quarks, leptons and elementary bosons.

The Standard Model of particle physics is the theory describing three of the four known fundamental forces (electromagnetic, weak and strong interactions – excluding gravity) in the universe and classifying all known elementary particles.It was developed in stages throughout the latter half of the 20th century, through the work of many scientists worldwide, [1] with the …

These particles have a variety of spins, both integral and half-integral, and their masses range from the value of 135MeV/c 2 for the neutral pion π 0 to 11020MeV/c 2 for one of the upsilon (heavy quark) states.
