Large-angle alpha-particle scattering from thin foils contradicted diffuse-charge atomic models and led Rutherford to a compact, positively charged nucleus.

Each relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
The unexpected backscattering required a compact concentration of positive charge and led to the nuclear atom.
The source experiment, observation, anomaly, or problem materially motivated the development, revision, or acceptance of the target concept. Historical influence is not logical derivation; the edge detail states the documented role and avoids retrospective origin myths.
wp-physics-geiger_marsden_gold_foil_experimentaps-rutherfordThis is an authored directed relation from the source endpoint to the target endpoint.
Rutherford’s atomic model was formulated specifically to explain the Geiger–Marsden angular distribution.
The source experiment, observation, anomaly, or problem materially motivated the development, revision, or acceptance of the target concept. Historical influence is not logical derivation; the edge detail states the documented role and avoids retrospective origin myths.
