Does Millikan's experiment support the theory of the electron?

Yes, Millikan's oil drop experiment provided strong support for the existence of the electron as a discrete particle. By measuring the charge of oil droplets influenced by electric fields, Millikan was able to determine the elementary charge of the electron. His findings confirmed that electric charge comes in quantized units, aligning with the theoretical framework of electrons as fundamental particles in atoms. This experiment was pivotal in solidifying the understanding of atomic structure and the role of electrons.
