what are baryons and leptons?

Hadrons come in two further groups, Baryons and Mesons. Baryons are hadrons that can decay into or are protons. ... Baryons and mesons aren't fundamental particles and so can be split into smaller particles known as quarks. Leptons − Leptons are particles that interact using the weak nuclear force.

Protons and neutrons, for instance, are themselves made up of elementary particles called quarks, and the electron is only one member of a class of elementary particles that also includes the muon and the neutrino.

Electrons are negatively-charged particles. But these basic atomic components are by no means the only known subatomic particles. However, quarks, muons and neutrinos, which make up major subatomic particles, will not be covered in this lesson.

Protons and neutrons are made up of fundamental particles of matter called quarks. Electrons are another type of fundamental particles of matter called leptons. Bosons are fundamental particles that carry forces between fundamental particles of matter.

Protons contain two up quarks and one down quark. Neutrons contain one up quark and two down quarks. The nucleus is held together by the "strong nuclear force," which is one of four fundamental fources (gravity and electromagnetism are two others).

Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus.

Hadrons are particles that feel the strong nuclear force, whereas leptons are particles that do not. The proton, neutron, and the pions are examples of hadrons. The electron, positron, muons, and neutrinos are examples of leptons, the name meaning low mass. Leptons feel the weak nuclear force.

Only two types of quark are needed to form protons and neutrons, however, and these, together with the electron and one other elementary particle, are all the building blocks that are necessary to build the everyday world. The last particle required is an electrically neutral particle called the neutrino.

For example, neutrino is comparatively smaller than an electron. ... The particle opposite to electron is positron having same mass as that of electron but carries opposite charge it is constituent of antimatter particle. Neutrino carry no net electric charge so they are called as neutrino.

Neutrons and protons are in the nucleus. There are no electrons in the nucleus. Note that a neutron is not composed of a proton and an electron. Some other particles that are not in the nucleus: positrons, neutrinos, antineutrinos, antiprotons, antineutrons, muons, etc.

Neutrinos all have less physical size (assuming they have it at all) than quarks. In the standard model, all the elementary particles are point particles (if they weren't points, we wouldn't consider them elementary).

Protons, neutrons, and electrons: Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.

The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks.

The muon is a negatively charged particle that is much like an electron but with a mass about 200 times larger. A “muonic” hydrogen atom forms when a muon orbits a proton. The muonic atom's orbits and energy levels follow the basic rules of the Bohr model and the quantum mechanical model of the atom.
226368
Tau, elementary subatomic particle similar to the electron but 3,477 times heavier. ... Like the electron and the muon, the tau is an electrically charged member of the lepton family of subatomic particles; the tau is negatively charged, while its antiparticle is positively charged.

What's smaller than an electron? ... And then those atoms are made up of protons, neutrons and electrons, which are even smaller. And protons are made up of even smaller particles called quarks. Quarks, like electrons, are fundamental particles, which means they can't be broken down into smaller parts.
