Question

scientific discoveries are often built on the previous findings of other scientists. millikans oil drop experiment occurred after thompsons cathode ray tube experiment. what did both of these experiments collectively determine about the atoms subatomic structure? check all that apply. atoms contain negatively charged particles. the electron has a positive charge. the electron has a specific mass. the proton has a negative charge.

Explanation:

Thompson's cathode ray tube experiment discovered atoms contain negatively charged particles (electrons). Millikan's oil drop experiment determined the electron's charge, enabling calculation of its specific mass using Thompson's charge-to-mass ratio. Both collectively show atoms have negative particles and electrons have specific mass.

Answer:

A. Atoms contain negatively charged particles, C. The electron has a specific mass
