Answer

Brief Explanations:

Thompson's cathode - ray tube experiment discovered electrons (negatively - charged particles). Millikan's oil - drop experiment determined the charge of an electron, from which the mass of an electron could be calculated. Electrons have negative charge, protons have positive charge.

Answer:

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