Question

1. describe thomsons, millikans, and rutherfords contributions to atomic theory. include their experiments if appropriate.

Explanation:

Thomson discovered the electron via cathode - ray tube experiments, proposing the plum - pudding model. Millikan measured the charge of an electron through the oil - drop experiment. Rutherford's gold - foil experiment led to the nuclear model of the atom, showing a small, dense nucleus with electrons orbiting.

Answer:

Thomson discovered the electron using cathode - ray tubes and proposed the plum - pudding model. Millikan measured the electron's charge with the oil - drop experiment. Rutherford, through the gold - foil experiment, proposed the nuclear model of the atom with a small, dense nucleus and electrons orbiting it.
