WebThe Geiger-Marsden Experiment (also called the Rutherford Gold Foil Experiment) disproved the plum pudding model of an atom and predicted instead that an ato... This experiment demonstrated that both air and solid matter could markedly scatter alpha particles. The apparatus, however, could only observe small angles of deflection. Rutherford wanted to know if the alpha particles were being scattered by even larger angles—perhaps larger than 90°. See more The Geiger–Marsden experiments (also called the Rutherford gold foil experiment) were a landmark series of experiments by which scientists learned that every atom has a nucleus where all of its positive charge and most of its … See more Contemporary theories of atomic structure The prevailing theory of atomic structure at the time of Rutherford's experiment was the "plum pudding model". This model was devised by William Thomson and further developed by J. J. Thomson.

Besides showing that an oscillatory discharge would magnetize iron, which happened already to be known, Rutherford determined that a magnetized needle lost some of its magnetization in a magnetic field produced by an alternating current.
