The diаgrаm belоw shоws аlpha particles being fired at a piece оf gold foil. Considering our current model of the atom and the evidence that most of the alpha particles went through the gold foil. At what point on the diagram below would support this evidence (point 1 or 2) and why? Because: Alpha particles bounce off the nuclei within the gold atoms, because the nuclei are much more massive than the alpha particles. The alpha particles are repelled when they come close to the nuclei, because both are positively charged. The alpha particles go straight through the atom, because it is mostly empty space.
