Millikan's contributions to the development of atomic theory is the determination of
charge on electron
positive rays
charge to mass ratio
cathode rays
Explanation
In 1910, Millikan successfully measured the charge of the electron to be 1.6 x 10\(^{-19}\)C.
Positive rays were discovered by Eugen Goldstein, in 1886.
J.J. Thomson discovered the charge-to-mass ratio of an electron in 1897:
Cathode rays were discovered by. J. J. Thomson
