What Charge Do Neutrons Have
A movie of a neutron. The 'u' stands for an upwardly quark, and the 'd' stands for a down quark.
Neutrons, with protons and electrons, make upwardly an atom. Neutrons and protons are institute in the nucleus of an cantlet.[1] [2] [3] Unlike protons, which take a positive charge, or electrons, which take a negative charge, neutrons have zero charge[1] [iv] which ways they are neutral particles. Neutrons bind with protons with the residual potent force.
Neutrons were predicted by Ernest Rutherford,[v] and discovered by James Chadwick,[6] [7] in 1932.[six] Atoms were fired at a thin pane of beryllium. Particles emerged which had no charge, and he called these 'neutrons'. They were afterward added to the modern image of the atom.
Neutrons have a mass of one.675 × 10-24chiliad,[8] which is a footling heavier than the proton.[8] Neutrons are 1839 times heavier than electrons.[viii]
Like all hadrons, neutrons are made of quarks. A neutron is made of two downward quarks and one upward quark.[two] [three] Ane upward quark has a charge of +two/3, and the ii down quarks each accept a charge of -one/3. The fact that these charges cancel out is why neutrons have a neutral (0) accuse. Quarks are held together by gluons.
Isotopes [modify | change source]
Neutrons tin can exist establish in almost all atoms together with protons and electrons. Hydrogen-1 is the only exception. Atoms with the same number of protons but a different number of neutrons are called isotopes of the same element.
The number of neutrons in an atom does not affect its chemical properties. However it affects its half-life, a measure out of its stability. An unstable isotope has a short half-life, in which half of it decays to lighter elements. By contrast, a stable isotope has a long one-half-life, much longer than that of an unstable isotope. The stability of an isotope is related to radioactivity: an unstable isotope can be highly radioactive.

Neutrons are the primal to nuclear chain reactions, nuclear power and nuclear weapons.
