According to the Standard Model of particle physics, a subatomic particle can be either a composite particle, which is composed of other particles (for example, a baryon, like a proton or a neutron, composed of three quarks; or a meson, composed of two quarks), or an elementary particle, which is not composed of other particles (for example ...

Quarks are spin- ⁠1/2⁠ particles, which means they are fermions according to the spin–statistics theorem. They are subject to the Pauli exclusion principle, which states that no two identical fermions can simultaneously occupy the same quantum state.

2025年2月14日 · The baryons and mesons are complex subatomic particles built from more-elementary objects, the quarks. Six types of quark, together with their corresponding antiquarks, are necessary to account for all the known hadrons. The six varieties, or “ flavours,” of quark have acquired the names up, down, charm, strange, top, and bottom.

2025年2月14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. Whereas quarks together form nucleons within the atomic nucleus, the electrons generally circulate toward

2024年1月6日 · The three subatomic particles in an atom are protons, neutrons, and electrons. Protons and neutrons, in turn, consist of elementary particles called quarks. Subatomic particles are the building blocks of atoms , the smallest units of matter that cannot be divided by any chemical means.

2025年2月14日 · Subatomic particle, any of various self-contained units of matter or energy that are the fundamental constituents of all matter. They include electrons, protons, neutrons, quarks, muons, and neutrinos, as well as antimatter particles such as positrons.

Quarks- any group of subatomic particles believed to be among the basic components if matter. Quarks are believed to be the fundamental constituents of matter, and have no apparent structure. They are the particles that make up protons …

Quarks and gluons are the building blocks of protons and neutrons, which in turn are the building blocks of atomic nuclei. Scientists’ current understanding is that quarks and gluons are indivisible—they cannot be broken down into smaller components. They are the only fundamental particles to have something called color-charge.

These particles occur in two basic types called quarks and leptons. Each group consists of six particles, which are related in pairs, or “generations”. The lightest and most stable particles make up the first generation, whereas the heavier and less-stable particles belong to the second and third generations.

Baryons and mesons are combinations of quarks and are considered subatomic particles. The most famous baryons are protons and neutrons. The other elementary particles are mediators of the fundamental forces. These mediator particles enable the matter particles to …
