Physics - General PhysicsIt is well known and well established by scientific observation that a free neutron radioactively decays into a proton plus an electron plus an anti-neutrino with a mean life time before decay of about 900 seconds. That established fact conflicts sharply with the ...
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
‘e’ represents an electron and it contributes to the negative charge of an atom. The absolute charge of an electron is the negative charge of 1.6×10-19 coulombs. The relative mass of an electron is 1/1836. Furthermore, the mass of an electron is 0. Discovery of Proton Proton was ...

The number of electrons, neutrons and protons in a species are equal to 10,8 and 8 respectively. The proper symbol of the species is A.16O8 B.18O8 C.18Ne10 D.16O2−8Submit The ratio of electron, proton and neutron in tritium is : A1:1:1 B1:1:2 C2:1:1 D1:2:1Submit ...
How do the masses of the proton and the neutron compare with the mass of the electron? Do the proton and the neutron have the same mass? Do the proton and the neutron have exactly the same mass? What is the difference between a neutron and a proton? Consider th...
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 ...
