neutron是中子，proton是质子，electron是电子。中子不带电，质子带正电，电子带负电。中子与质子通过强相互作用结合，形成原子核，电子在核外运动
Neutron, neutral subatomic particle that, in conjunction with protons, makes up the nucleus of every atom except ordinary hydrogen (whose nucleus has one proton and no neutrons). Along with protons and electrons, it is one of the three basic particles ma
It is shown that it is possible to describe the electron and the proton at rest within the framework of Dirac's relativistic theory of particles as electro﹎agnetic stable, spheroidical particles like balloons with very thin envelopes. Their properties, especially their spins and their magnetic ...
In case of excessive neutrons outside the stability region, one neutron in the nucleus will be converted to proton by the emission of a negatively charged electron and an anti-neutrino ((ν))¯−e, which increases the proton number, and decreases the neutron number by one. Electrons ...
Original nucleus model in the 1920s was internal electron theory that the atomic nucleus is constituted by protons and electrons, and Rutherford already suggested in 1920 that an electron-proton pair could be bound in a tight state. Both of which were forgotten after the introduction of neutron ...
IT has recently been suggested by Bondi and Ly ttleton1,2 that the magnitudes of the electric charges on the proton and electron may differ by a little more than one part in 1018, in which case electrostatic forces would cause the universe to expand. In
proton (which has a mass essentially equal to the neutron mass), the proton is set into motion and the neutron comes to rest. Because the proton (unlike the neutron) is achargedparticle, it rapidly loses its energy through electric interactions with atomic electrons. Even if the collision is...
to W. D. Harkins2by Glasstone3. It appears likely that it was not used by either Rutherford or Hawkins before about 1920. In both cases, the neutron was a hypothetical combination of a hydrogen nucleus (also called a ‘positive electron’ or ‘proton’) and an ordinary negative electron....
