A neutral atom must have equal numbers of protons and electrons, so the atomic number of an element also gives the number of electrons. Helium has 2 protons, so its atomic number is 2. Atoms are neutrally charged, so what links atomic number and the number of electrons? electron proton ...
The discovery of neutron didn’t happen until the year 1932. James Chadwick discovered the neutron. He used scattered particle to calculate the mass of the neutral particle. The subatomic particle “neutron” is present in an atom’s nucleus.“n” represents neutron. It is a neutral particle....
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
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
