He discovered that the weight of an electron is 1836 times smaller than that of a hydrogen atom (atomis mass of 1)
Robert A. Millikan was the first to determine the electrical charge of the electron.
Robert A. Millikan conducted many experiments throughout his long, distinguished career. If you're referring to the famous "oil drop" experiment that measured the quantum of electric charge, Millikan and Harvey Fletcher performed that particular one in 1909.
he did not develop anything regarding the 'atomic theory' for he was against that theory.
Robert Millikan measured the electrical charge of the electron.
1955

Any, Robert Millikan determined the electrical charge of electron.
He developed the "ELECTOMAGNETISM"
discovering artificial radioactivity
he drew pictures about it :) <3
he came up with the theory of atomic numbers
Im sorry 4 not being completely sure, but................. Newton believed in atomic forces. He thought that atoms and atomic power could not be properly understood without the use of quantum mechanics. -Sorry TJ
