Kinds of charged particle :

• antiproton (7 facts) - The antiparticle of a proton, identical in mass and spin but of opposite (negative) charge.
• antiquark (5 facts) - The antiparticle of the quark.
• cosmic rays (6 facts) (corpuscular radiation) - High-energy charged particles which stream at relativistic velocities down to Earth from space. The Sun ejects low-energy (10⁷ - 10¹⁰ eV) cosmic rays during solar flares (those of lower energy than this are unobservable from Earth because of solar system magnetic fields). Those of intermediate energy (10¹⁰ - 10¹⁶ eV) have an isotropic distribution, and are apparently produced in the Galaxy. Possible sources of acceleration are shock waves accompanying supernovae (although cosmic rays have a higher hydrogen content than would be expected from a star that has processed material to iron), and the rotating magnetic fields of pulsars. The light elements Li, Be, and B have a higher abundance ratio in cosmic rays than in the solar system.
• deuteron (6 facts) (d) - The nucleus of deuterium, an isotope of hydrogen. It consists of one proton and one neutron bound together., The nucleus of a deuterium atom. m_d = 2.01355 amu.
• electron (9 kinds, 35 facts) - Negatively charged fundamental particle (also called a beta particle) found in the atoms of all elements, where it "orbits" (at different energy levels and with different directions of spin) round the central nucleus. The combined charge of the orbiting electrons is balanced (in a neutral atom) by the charge of an equal number of positively charged protons in the atomic nucleus. An electron is also the fundamental unit of electricity., A small, negatively charged particle that appears in every neutral atom, surrounding the positively charged nucleus like bees around honey., A negatively charged spin-1/2 particle, which interacts via the electromagnetic, weak and gravitational forces. It has a mass of 0.511 MeV / c², some 1800 times lighter than the proton., A lepton with an electric charge of -1. An electron is also a fermion because it has a spin of one half., A stable, negatively charged elementary particle - the lightest massive particle known. The classical electron radius is 2.82 × 10^-13 cm; m_e = 9.1 × 10^-28 g = 5.48597 × 10^-4 amu. The electron family (see lepton) includes the electron e^-, the positron e⁺, the electron neutrino ν_e, and the electron antineutrino ν_ebar. Rest-mass energy of electron 8.186 × 10^-7 ergs. Electron charge = 1.60219 × 10^-19 coulombs., Light elementary particle with a negative electrical charge. Electrons are found in shells surrounding the nuclei of atoms; their interactions with the electrons of neighboring atoms create the chemical bonds that link atoms together as molecules.
• ionized methylidyne (4 facts) (CH⁺)
• muon (9 facts) (μ) - A second-generation lepton. It is essentially a more massive electron., Short-lived elementary particle with negative electrical charge. Muons are leptons. They resemble electrons, but are 207 times more massive., An elementary particle, formerly called a mu-meson but now classified with the leptons because it seems to be identical with the electron except for its much greater mass (207 times that of an electron). The muon family includes the muons and their neutrinos (and their antiparticles). Muons may have a positive or a negative charge., Elementary particles produced when cosmic rays enter the upper atmosphere.
• nucleus (12 kinds, 54 facts) - The central part of an atom, composed of protons and neutrons (which are made of quarks) and containing nearly all of each atom's mass., The massive, positively charged central part of an atom, composed mainly of protons and neutrons, around which the electrons revolve. The radius of an atomic nucleus is directly proportional to the cube root of its mass. Density at least 10¹⁴ g cm^-3. Radius 10^-12-10^-13 cm.
• pi+ (5 facts)
• pi- (5 facts)
• positron (10 facts) (antielectron) - The antiparticle of the electron, discovered by Anderson in 1934. It has the same mass and spin as the electron, but opposite charge and magnetic moment.
• proton (13 facts) (p) - A subatomic particle with positive electric charge. Every atom has at least one proton in its nucleus; the number of protons determines the element. For example, all atoms with one proton are hydrogen, all atoms with two protons are helium, and so on., One of the constituents of the atomic nucleus. It is a spin-1/2 particle carrying positive electric charge. The proton is the lightest baryon and, as a result, is the particle into which all other baryons eventually decay. It is believed to be absolutely stable, but certain theories (GUTs) predict it will decay very, very slowly., A baryon made of two up quarks and a down quark. It possesses a positive electromagnetic charge and can only be found in atomic nuclei. A single proton is a hydrogen nucleus., A massive particle with positive electrical charge found in the nuclei of atoms. Composed of two up quarks and one down quark. The proton's mass is 938.3 MeV, slightly less than that of the neutron., A positively charged elementary particle; the nucleus of a hydrogen atom. Mass of proton 1.00728 amu = 1.6726 × 10^-24 g = 1836.12 m_e.
• quark (9 kinds, 37 facts) - The hypothetical constituent of the elementary particles that interacts via glue forces. Originally only three quarks were hypothesized; today it appears that six are required. For a variety of theoretical reasons, free quarks can never be seen., Fundamental particle of which protons, neutrons and electrons are now thought perhaps to be made up. There are possibly three or four types of quark. It is even possible that quarks themselves may be made up of still more fundamental particles., A sub-atomic particle which is a fundamental building block of the hadrons., A fermion with fractional electric charge., A particle that is acted upon by the strong force. Quarks exist in six varieties: up, down, charm, strange, top, bottom and three "colors" (red, green, blue)., One of the fundamental, indestructible particles of nature, out of which many other subatomic particles are made. Five types of quarks have been discovered, and it is believed that a sixth also exists. Quarks interact mainly via the strong nuclear force and the electromagnetic force., Fundamental particles from which all hadrons are made. According to the theory of quantum chromodynamics, protons, neutrons, and their higher-energy cousins are composed of trios of quarks, while the mesons are each made of one quark and one antiquark. Held together by the strong nuclear force, quarks are not found in isolation in nature today; see asymptotic freedom.
• tau (5 facts) (τ)
• triton (6 facts) (T) - The nucleus of the tritium atom.
