Milikan used ______________ in his atomizer?
Correct answer: C. Oil
- A. Milk
- B. Honey
- C. Oil
- D. Water
Explanation
Millikan used tiny oil droplets in his oil-drop experiment to measure the electronic charge. The droplets were sprayed with an atomizer and their motion was observed between charged plates. Students may choose d because water can also be sprayed into droplets, but water droplets evaporate too quickly for accurate measurement.

About Discovery of the Proton
The discovery of the proton follows the study of positive rays, also called canal rays, observed in discharge tubes and later identified as positively charged particles. The work of Goldstein and Rutherford is linked to the proton's charge, relative mass and role in the nuclear model, distinct from the discovery of the electron.
