Understand that the proton is a subatomic particle found in the nucleus of an atom, carrying a positive charge.
Recall the historical experiments related to atomic structure, especially those involving the nucleus.
Identify Ernest Rutherford as the scientist who conducted the gold foil experiment, which led to the discovery of the atomic nucleus and the proton.
Note that James Chadwick discovered the neutron, Niels Bohr developed the Bohr model of the atom, and J.J. Thomson discovered the electron.
Conclude that Ernest Rutherford is credited with the discovery of the proton based on his experimental work.
