Neutronen (n) är en subatomär partikel som tillsammans med protoner bildar en atomkärna. Olika antal neutroner i kärnan ger upphov till olika isotoper av ett grundämne. Neutronen har ingen elektrisk laddning, den är neutral, har spinn ½, och massan 939,573 MeV/c² (1.6749 × 10 −27 kg, eller 1,00866490 u, aningen mer än protonen).

17 Nov 2017 An electron's mass is approximately 2000 (sometimes guessed at around 1840) times smaller than the mass of a proton. Neutrons have the 

The mass of neutron in the atomic mass unit is 1.008664. You will be surprised when you will know that the proton and the neutron have nearly the same mass while electron has less mass. Where, Neutron = 1. Proton = 0.99862.

Born from the explosive death of another, larger stars, these tiny objects pack quite a punch. Se hela listan på energyeducation.ca Neutron definition is - an uncharged elementary particle that has a mass nearly equal to that of the proton and is present in all known atomic nuclei except the hydrogen nucleus. It has about the same mass and diameter as a proton. Neutrons are found in all atoms except for most atoms of hydrogen. All the atoms of a given element have the same number of protons and electrons, but they may vary in their numbers of neutrons. Atoms of the same element that differ in their numbers of neutrons are called isotopes.

It is a basic component of all atomic nuclei except the protium isotope of hydrogen. [ neutr (al) + -on.] 2018-01-16 When the core of a massive star undergoes gravitational collapse at the end of its life, protons and electrons are literally scrunched together, leaving behind one of nature's most wondrous creations: a neutron star.

Neutronium is used in popular physics literature to refer to the material present in the cores of neutron stars (stars which are too massive to be supported by electron degeneracy pressure and which collapse into a denser phase of matter).
