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
1.What is a proton, neutron, and electron?什么是质子,中子和电子?The proton is a subatomic particle with an electric charge of +1 elementary charge.The neutron is a subatomic particle with no net electric charge and a mass slightly larger than that of a proton.Proton and neutron are usually...

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

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 ...
