WebGostaríamos de lhe mostrar uma descrição aqui, mas o site que está a visitar não nos permite. WebIn his 1911 paper , Rutherford assumed that the central charge of the atom was positive, but a negative charge would have fitted his scattering model just as well. In a 1913 paper, [27] Rutherford declared that the "nucleus" (as he now called it) was indeed positively charged, based on the result of experiments exploring the scattering of alpha particles in …
