It didn't.
J. J. Thomson discovered the electron in 1897. He calculated the charge-to-mass
(
In 1904, he proposed the plum pudding model, in which the electrons were immersed in a positively charged "pudding".
In 1909, Millikan performed his famous oil drop experiment and determined the charge (
The gold foil experiment was performed in 1909. It wasn't until 1911 that Rutherford wrote his paper proposing the nuclear model of the atom.
So Millikan's oil drop experiment didn't change the model of the atom.
