The observation of such large-angle scattering implied that the positive charge and the majority of the atom’s mass were concentrated in a tiny, central region, creating an intense electric field capable of repelling the positively charged alpha particles. By directing a beam of alpha particles at a thin sheet of gold foil, Rutherford and his colleagues Hans Geiger and Ernest Marsden uncovered the existence of a small, dense, positively charged nucleus, a discovery that reshaped the trajectory of modern physics.
From Plum Pudding to Nuclear Atom: Rutherford's Revolutionary Experiment
Interpretation and the Nuclear Model Rutherford interpreted these surprising results in 1911, proposing a revolutionary model of the atom. Surrounding the foil was a circular fluorescent screen coated with zinc sulfide, which emitted a tiny flash of light, or scintillation, whenever it was struck by an alpha particle.
This discovery overturned the plum pudding model and established the foundational concept of a nuclear atom. Prior to this investigation, the prevailing atomic theory was J.

These particles then collided with an extremely thin gold foil, typically only a few hundred atoms thick, ensuring that the particles would pass through with minimal interactions. The electrons, being much lighter, occupy the vast space surrounding this nucleus, orbiting it at a distance.
