Millikan: He discovered that the weight of an electron is 1840 times smaller than a hydrogen atom (atomis mass of 1)
Thomson: Thomson was the first person to suggest the theory of the atom containing positive and negative particles, and demonstrated the latter which called electrons

∙ 14y agoRobert Millikan (1909)- Determined unit charge of the electron with his oil drop experiment in 1909. This allowed calculation of the mass of electrons and positively charged atoms

∙ 11y agoWith the combined results of Thomson and Millikan, a value for the electron mass was obtained
------------------------------------
J J Thomson determined the specific charge of the electron
But Millikan with his oil drop experiment determined the charge of an electron
So it is easier for us to determine the mass of an electron
Thanks to both scientists.
