13 set 1911 ano - Rutherford
Descrição:
Rutherford created the planetary model of the atom.
He discovered what a nucleus is, and realized it's positively charged. "Rutherford tested Thomson's hypothesis by devising his "gold foil" experiment. Rutherford reasoned that if Thomson's model was correct then the mass of the atom was spread out throughout the atom."
