Question

question 1. match each experiment to its key discovery or result by dragging the correct statement to the appropriate experiment. j. j. thomsons cathode - ray tube experiment millikans oil - drop experiment rutherfords gold foil experiment determined the charge of an electron. showed that atoms contain negatively charged particles called electrons. proved that atoms have a small, dense nucleus at their center.

Explanation:

J. J. Thomson's Cathode - Ray Tube Experiment showed that atoms contain negatively - charged particles called electrons. Millikan's Oil - Drop Experiment determined the charge of an electron. Rutherford's Gold Foil Experiment proved that atoms have a small, dense nucleus at their center.

Answer:

J. J. Thomson's Cathode - Ray Tube Experiment: Showed that atoms contain negatively charged particles called electrons.
Millikan's Oil - Drop Experiment: Determined the charge of an electron.
Rutherford's Gold Foil Experiment: Proved that atoms have a small, dense nucleus at their center.
