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 … WebIn the now well-known experiment, alpha particles were observed to scatter backwards from a gold foil.

"WebRutherford was gradually turning his attention much more to the α (alpha), β (beta), and γ (gamma) rays themselves and to what they might reveal about the atom. That is, he was leaving radio-chemistry to others and turning to physics. Rutherford always gathered a group of bright young researchers around him. " - How did rutherford envisioned the atom

WebThe statement in the video is wrong. In 1897, J. J. Thomson used an electric field (V) to accelerate electrons into a magnetic field (B). The magnetic field deflected the electrons into circular paths of known radius (r).
