The muon (from the letter mu (μ)--used to represent it) is an elementary particle with negative electric charge and a spin of 1/2. It has a mean lifetime of 2.2μs, longer than any other unstable lepton, meson, or baryon except for the neutron. Together with the electron, the tau, and the neutrinos, it is classified as a lepton. Like all fundamental particles, the muon has an antimatter partner of opposite charge but equal mass and spin: the antimuon, also called a positive muon. Muons are denoted by μ− and antimuons by μ+. For historical reasons, muons are sometimes referred to as mu mesons, even though they are not classified as mesons by modern particle physicists. Muons have a mass of 105.7 MeV/c2, which is 206.7 times the electron mass. Since their interactions are very similar to those of the electron, a muon can be thought of as a much heavier version of the electron. Due to their greater mass, muons do not emit as much bremsstrahlung radiation; consequently, they are highly penetrating, much more so than electrons. Muons have a life of about 2 nanoseconds.

A particle in a atom that has a negative charge is a?
Electrons and down quarks have negative charge, as do strange and bottom quarks, along with muons and taus.
What is the difference between a muon and a meson?
all particles in particle physics are divided into two sub groups the hadrons and leptons the difference between them being that baryons interact by strong force leptons interact by weak force the hadron group can be further subdivided into two more groups the mesons and baryons muons are part of the lepton group
Was a new electron discovered?
... no? The reason for the question mark is that I'm trying to figure out what on Earth you might mean by "new electron". Muons and tau particles are somewhat similar to electrons, but calling them "new electrons" is a bit of a stretch. They've also been known for quite a while; the muon was discovered in 1936 and the tau has been known since the late 1970s.
What is the muon's mass?
Muons decay by various methods, primarily, due to the weak interaction, into an electron and two neutrinos. The mass of the muon is 105.7 MeV/c2, with the mass of the electron being 0.511 MeV/c2, and the mass of the neutrino is less than 2.2 eV/c2. As a result, the loss of mass from muon decay, which is carried away as energy, is around 105.2 MeV/c2.
What type of radiation has the shortest wave length?
If this question if referring to electromagnetic radiation (light) then the sun probably emits very small amounts of gamma rays, which have the shortest wavelengths of all electromagnetic radiation as well as larger amounts of x-Rays (the next wavelength larger). However, there are a variety of particles with larger masses and higher energies than that of photons. These particles are known as cosmic rays, which include electrons, muons, protons, neutrons, and even whole helium nuclei (called alpha particles). These higher mass particles can travel at near-light-speed velocities and as a result have very short wavelengths.
How do isotopes gain stability?
Through neutron bombardment. Muons produce neutrons and isotopes can be naturally stabilized via muons
How do pions decay into muons?
Negatively charged pions decay into muons and muon anti-neutrinos via the weak nuclear interaction. The probability of such a decay occurring is approximately 99.98%. Muons can also decay into electrons and electron anti-neutrinos, but the probability of such a thing occurring is only about 0.012% Positively charged mouns decay into anti-muons and muon neutrinos instead. Neutral pions decay into either two photons or a photon and one electron and one positron. One decay of a negatively charged pion produces one muon and one muon anti-neutrino.
What are examples of hadrons?
Electrons, muons, and taus having negative charge and a distinct mass each .
What part do particles play in radiation?
Particle radiations: alpha particles, beta particles, positrons, neutrons, protons, muons, neutrinos, etc.
A particle in a atom that has a negative charge is a?
Electrons and down quarks have negative charge, as do strange and bottom quarks, along with muons and taus.
What are the smaller particles that make up muons?
A Muon is currently considered an 'elementary particle', it has no known components. If a Muon is made out of smaller particles, they are unknown.
The atomic subunit that has a negative charge is the?
Electrons and down quarks have negative charge, as do strange and bottom quarks, along with muons and taus.
What has the author Colm O'Sullivan written?
Colm O'Sullivan has written: 'Some properties of a neutral component of the cosmic radiation' -- subject(s): Cosmic rays, Muons, Spark chamber
What is smaller than the periodic table of elements?
Particles smaller than elements are called sub atomic particles. Among these are: Protons, Neutrons, Electrons, Photons, Gluons, Mesons, Bosons, Muons, Quarks, and more.
What is the smallest particle known to man?
I believe that would be the electron. Edit by Ylesrinne Not quite. Electrons are made of quarks, which are smaller than electrons allong with muons, gloums, leptoms, femioms, tracheons, among others.
Which particle in a atom has a negative charge?
Electron
What is in the center of the atom?
Nucleus. Composed of Protons and neutrons. Can be sub-divided further but you probably don't have to know that. (quarks and muons and such.)
