A bradyon (or tardyon) travels slower than the speed of light in vacuum and has a non-zero, real rest mass.A luxon travels as fast as light in vacuum and has no rest mass.A tachyon is a hypothetical particle that travels faster than the speed of light so they would paradoxically experience time in reverse (due to … See more This is a list of known and hypothesized particles. See more Elementary particles are particles with no measurable internal structure; that is, it is unknown whether they are composed of other particles. They are the fundamental objects of quantum field theory. Many families and sub-families of elementary particles exist. … See more Quasiparticles are effective particles that exist in many particle systems. The field equations of condensed matter physics are remarkably similar to those of high energy particle physics. As a result, much of the theory of particle physics applies to condensed matter … See more • Chameleon particle a possible candidate for dark energy • Acceleron particle another candidate for dark energy See more Composite particles are bound states of elementary particles. Hadrons Hadrons are defined as strongly interacting composite particles. Hadrons are either: • Composite fermions (especially 3 quarks), in which case they … See more The following categories are not unique or distinct: For example, either a WIMP or a WISP is also a FIP. • A WIMP (weakly interacting massive particle) is any one … See more • Calorons, finite temperature generalization of instantons. • Dyons are hypothetical particles with both electric and magnetic charges.

Mass in special relativity - Wikipedia
Webatomic mass unit. one-twelfth of the mass of a carbon atom having six protons and six neutrons. atomic mass. the weighted average of the masses of the isotopes of an element. isotope. atoms with the same number of protons, but different numbers of neutrons in the nucleus of an atom. WebRelative mass of electrons = 0.0005 (this gets rounded to zero). Atoms: Relative mass = number of protons + number of neutrons. Atomic Number and Mass Number The mass number of an atom (also called relative mass) is the total number of protons and neutrons in a nucleus. The atomic number of an atom is the number of protons in the atom. boys thermal underwear set
