Subject Rutherford model of the atom E168968 entity
Predicate basedOn P98 FINISHED
Object Rutherford gold foil experiment
The Rutherford gold foil experiment was a landmark early 20th-century physics experiment in which alpha particles were fired at thin gold foil, revealing the existence of a small, dense, positively charged atomic nucleus and overturning the plum pudding model of the atom.

Target entity: Rutherford gold foil experiment
Context triple: [Rutherford model of the atom, basedOn, Rutherford gold foil experiment]
  • A. Rutherford model of the atom
    The Rutherford model of the atom is an early nuclear atomic model proposing a tiny, dense, positively charged nucleus surrounded by mostly empty space in which electrons orbit.
  • B. Franck–Hertz experiment
    The Franck–Hertz experiment is a landmark early-20th-century physics experiment that provided direct evidence for the quantization of atomic energy levels, supporting the Bohr model of the atom.
  • C. Davisson–Germer experiment
    The Davisson–Germer experiment was a landmark 1927 physics experiment that demonstrated the wave nature of electrons through diffraction from a nickel crystal, providing key evidence for quantum mechanics and wave–particle duality.
  • D. oil-drop experiment
    The oil-drop experiment was a landmark early 20th-century physics experiment that measured the elementary electric charge of the electron by observing tiny charged oil droplets suspended in an electric field.
  • E. Cockcroft–Walton experiment
    The Cockcroft–Walton experiment was a pioneering 1932 nuclear physics experiment that achieved the first artificial disintegration of atomic nuclei using accelerated protons, confirming Einstein’s mass–energy equivalence.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
