Ernest Rutherford (1 jan 1871 ano – 1 jan 1937 ano)
Descrição:
Ernest Rutherford (1871-1937) was the British physicist that disproved Thomson's Plum Pudding Model by conducting a series of experiments, titled the Gold Foil Experiment (1911), with the help of Ernest Marsden and Hans Geiger, in which they aimed alpha particles at solid objects, such as gold foil, and observed how they reacted passing through. They were surprised to find that, while most of the particles passed through as expected, some particles reflected at an angle and others even reflected straight back, causing Rutherford to conclude that an atom is a small, dense positively-charged nucleus, centered in the atom, surrounded by a field of negatively-charged electrons, called the Rutherford Model.
