Ernest Rutherford is credited with the discovery of the proton. In 1909, his experiments led to the understanding that the hydrogen atom's nucleus consisted of a positively charged particle, which he named the proton.
Ernest Rutherford's Contribution
Rutherford's gold foil experiment was pivotal in this discovery. By observing how alpha particles scattered when passing through a thin gold foil, he deduced the existence of a small, dense, positively charged nucleus within the atom. He later concluded that the nucleus of the hydrogen atom—the simplest atom—was this fundamental positive particle, the proton.
- Gold Foil Experiment: This experiment revolutionized our understanding of atomic structure.
- Hydrogen Nucleus: Rutherford identified the proton as the nucleus of the hydrogen atom.
- Positive Charge: He established that the proton carried a positive electrical charge.
Several sources confirm Rutherford's role:
- Vedantu: Explicitly states that E. Rutherford discovered the proton in 1909. Discovery of Electrons, Protons and Neutrons
- Byjus: Credits Ernest Rutherford with the discovery of the proton, noting his proof that the hydrogen atom's nucleus is a proton. Discovery of Proton and Neutron - Who Discovered and How Proton ...

- Wikipedia: Details Rutherford's extensive contributions to nuclear physics, solidifying his role in proton discovery. Ernest Rutherford - Wikipedia
Therefore, while others contributed to our understanding of atomic structure, Ernest Rutherford is rightfully considered the discoverer of the proton.
