Answer 1

Millikan C

Hope this helps you out!

Answer 2

B. Robert Millikan

Step-by-step explanation:

J.J. Thompson gave the plum pudding model of the atom.

Millikan determined the charge and mass of an electron. Millikan’s oil drop experiment was conducted to measure the elementary charge ( or a unit charge).

Eugen Goldstein discovered the anode rays or protons.

Rutherford conducted the gold foil experiment and proved that the center of the nucleus has a positive charge and most of the atom’s mass lies in a small volume.
