The charge on an electron was determine by ________________?
Correct answer: C. Millikan
- A. Ampere
- B. Maxwell
- C. Millikan
- D. Thomson
Explanation
Millikan measured the elementary charge using the oil-drop experiment, finding its magnitude to be about 1.6 x 10^-19 C. Thomson discovered the electron and measured its charge-to-mass ratio, so choosing Thomson confuses two different experiments.

About Composition of Atomic Nuclei
Atomic nuclei contain positively charged protons and electrically neutral neutrons, collectively called nucleons. Questions use atomic number, mass number and nuclear notation to identify isotopes, isobars and isotones, and may connect nuclear composition with nuclear charge, mass defect, binding energy and the stability of the nucleus.
