Question

Based on the data gathered in Millikan's oil-drop experiments, the concept of atomic structure was modified. Which of the following aspects of the structure of the atom was validated by these experiments?1.mass of the atom2.mass of an electron3.charge on an electron4.charge on a proton5. mass of a proton

Answer 1

Answer:

3. Charge on an electron

Explanation:

Millikan and Fletcher could measure the charge on the oil droplets.

When they repeated the oil drop experiment many times, they found that the charges were integral multiples of 1.59 × 10⁻¹⁹ C.

They proposed that this was the charge on an electron.
